If you downloaded from the MAS, download it again. if you downloaded it from another source, steer clear.
I downloaded it from the app store thru the public Beta program. Now I can't seem to re-download it.
Remove the app "Install OS X Yosemite Beta" from Applications, clear the Trash and try to see if it works to download the app again from the App Store

Still having the problem
I have verified that the date, time zone and time are correct on my computer.
The last download was done via ethernet and still no luck.
I haven't reset the time using terminal, don't know how. This is what I get.......
