    Can't open PDF.  Program does not have valid digital signature. No valid Acrobat S/N found.


      I recently bought new HP computer with Windows 7.  I loaded my Adobe Creative Suite 2 Premium.  Illustrator tries to open then just disappears.  I can not open PDF's.  Get the following message:  This program doesn't have valid digital signature that verifies it's signature.  No valid Acrobat S/N found. Acrobat will now quit.  Then: There is a problem with Adobe Acrobat/Reader. Please exit and try again.  When I exit - computer locks up.
