HELP ! iDisk loose all my data (after disconnect to mm)??

[fa.ce]

I've tried to syncronize 1 giga of data (many little files).
iDisk stop to syncronize from my iDisk's desktop into mobile me iDisk.
I've so disconnect my mobile me account from preferences and reconnect.
My iDisk disappear and is created automagically a new iDisk on my desktop.
Old iDisk desktop is shown but seems impossible to open it, how to do that ?

Login to me.com/idisk and check that your data is there. If it is, then it's just a matter of rebooting or running a permissions check via Disk Utility.

Thanks for the quick reply.
My problem is a little bit different.
I've many files as said and move them all into my iDisk's desktop.
Then startup the syncronization process with iDisk.
Unfortunately the syncronization process wasn't completed.
So i disconnect my mm account and reconnect.
Now on mobile me i've not all the files, i hope that all the files are into desktop but seems unavaible.
I try to open my old iDisk on desktop but is shown 'open with' message box.
Which program i've to select to open it ?
Hope is clearer now ...
Thanks
