Acrobat XI "Not Responding" when Launched

The hang time varies - it's been as long as 60 seconds - but there's an issue every time I open a PDF with Acrobat.  The only exception is if I already have Acrobat open with another document.  There are no updates available (11.0.05) and I've uninstalled/reinstalled.  I'm using Windows 7 Home Premium and CC.

Any ideas?

Thanks in advance.  Hope everyone's having a great day!
