Acrobat not works - Adobe Application Manager is corrupted

Hello,

I have Acrobat Pro 11 that was bought two years ago and successfully used couple of months.

Now, after long break I'm trying to use it again. It works a few days but then says "Your Adobe Application Manager is corrupted... Please download it from ... URL" (I'm using Ukrainian version the quotation may be inaccurate).

URL = http://www.adobe.com/go/adobeapplicationmanager_ua

But this link is broken.

I’m reinstall Acrobat a few times but it not help.

What should I do to fix this problem and use Acrobat normally?

Please help.

PS. I already have Adobe account and already register my Acrobat there.
