An error Occured

I got the same error the first day Yosemite Beta was available, but today I can grab a copy quickly and easily.
Most the time this is a network time out. My experience has been this occurs because everyone is trying to download at the same time and we're overwhelming the Apple servers.
In your case, since I'd assume everyone has long ago finished downloading Yosemite, your network connection is suspect.

What should I do then? There isn't any other option for it to redownload as you see the button seems to disappear. I have a decent internet speed also.
If you have more than one Mac using the same iCloud ID you can copy from there.
Or try logging in and out of the App Store, let it refresh the purchased list
That actually is my main prob. Loggin in and out won't refresh the purchase list even when changing country store.
Heres what I did:
1. Created a new admin user account
2. Use that account and logged in my apple account
Problems:
- Code already redeemed
- Purchases tab does not show anything
Strange.... I did the same, just for kicks, created a new Admin account, authenticated with the same Apple ID and I see all my purchases including Yosemite Beta.
I'm stumped.
Download both Yosemite AND Mavericks simultaneously. Try this and see if it works. You don't have to install Mavericks, just hit 'quit' or cancel when it asks you whether you want to install it or not, and proceed to install Yosemite.
This worked for me and a bunch of other people here too.
Downloading Mavericks gave me this error:
As for the Yosemite, I cannot redownload it since there is this error hanging:
Which does not disappear..
Take a look at this link https://discussions.apple.com/thread/4483444 
One of the ways that worked
1. Followed this link.http://support.apple.com/kb/HT4928
2. In the mac app store I dropped down the menu from the top bar "store"
3. Logged out
4 Logged in
5. Went to view my account - under store
6. Found the unhide purchace button.
7. Clicked that
8. Went back to purchaces - Button had changed but error text was still there.
9. Went to Store ~ Check for unfinished downloads.
10. It gave me the option to resume
Maybe just try step 9 than 10 first

Try loggin out and then log back in, and then try again? Or shut down your computer, boot up, log out, log into the MAS.
My Account Information does not have the unhide hidden purchases. *Maybe because I have no hidden purchases?Take a look at this link https://discussions.apple.com/thread/4483444

Checked the MAS as well. Nothing.
Did this for days now. Still having the same thing. I even had changed my store country once just to (maybe) reset it or something but does not help.

don't know if this has been posted - but what about trashing the mac app store plist file?
Go into Finder > hold down Option key and click Go and then Library. When you're here > go into Preferences and find the com.apple.appstore.plist file and drag it into the trash but don't empty trash.
Reboot your computer and try opening the Mac App Store with a fresh new plist.

Tried twice to make sure that I did the instruction but after loggin in to app store, I have the same purchase list (image show in previous posts) with something-like-disabled button and a red text that says 'An Error Occured'
After the other steps here that others have suggested, creating another admin account then logging into the Mac App Store (Apple menu -> App Store) should have taken care of it if it was an issue with a user preference file. By the way, does downloading Mavericks in the new account work, or does it give the error too?
More drastic measures could be to reinstall Mavericks, but then you're going to be installing a new system with Yosemite anyway.
If anything, I would try logging into the Mac App Store from a totally different Mac. Maybe even at a different location or ISP. This would narrow down if the issue is with 1) your ISP, 2) your Mac/current OS, or 3) if it's with your Apple Store account/purchases. If it's with your account, that's something only Apple would be able to help with.
If you can download it from another Mac, hopefully you could then copy/flash drive/transfer the installer to your Mac and upgrade to Yosemite and hopefully resolve the issue.
Note: Make sure you sign out of the Mac Store on those other Macs that aren't yours when you are done.

You have an Air
If I was in your situation, and had an Apple Retail Store neartby, I would:
1) Bring Air to ARS
2) Use the wifi to check Mac App Store account on Air, just in case it was an ISP issue. If it still has the error
3) Sign into Mac App Store on one of their computers.
4) Check to see if Yosemite is downloadable or if the error is still on the App Store account.
5) If it's downloadable, let it finish, then AirDrop the installer back to your Mac.
6) Sign out of the Mac App Store on the ARS Mac.
Like I mentioned above, if your account on their Mac still shows the error, there might be something amiss with your account that's causing the error.

Sadly, Im the only one among my friends have a mac.
Great thanks! Im gonna try this and will post the error here.
Edit: Finally installed Yosemite on my MBA. What I did is use different ISP and create a new account on my MBA and also created a new Apple ID and use it with the newly created MBA account.
This post can be closed now. Thanks for the people who bothers to replied here.

I don't know if you ever fixed this issue, I came across this tech tip today and remembered this issue.

Might work, OS X Daily is usually very good.
