I am suddenly experiencing a similar problem in Acrobat XI Standard - after flawless operation for the last 10 months.   Nothing has changed in my Adobe setup.

I have tried to reset preferences but this does not seem to work.  I completely uninstalled Adobe XI Standard this afternoon and reinstalled.  This worked for a few hours but now it's back to freezing.
I open up a PDF file but it freezes when I try to scroll or change pages - Adobe Acrobat (Not Responding).

Eventually - after it blanks out - a dialog box asks me to wait, or close.  The Problem Details Box shows the following:

did you successfully reset your preferences?

[Merry_hearted15A7]

No, that did not work.  I moved the Preferences folder to TEMP but Adobe still froze upon restart ... I put the Preferences folder back
