Acrobat 9.4.4 Pro Crashes When Attempting to Open PDF Form

OS: Win XP Pro SP3

The machine worked fine until Acrobat updated itself to 9.4.4 then the problem started.  Crashes when attempting to open most PDF Forms - even when freshly rebooted or repaired.  I originally thought it was related to a browser or Outlook 2007, but later found that it does it under all circumstances.  It is my General Manager's machine having the problem, so I need to get this resolved ASAP.  Your experience and assistance is much appreciated.

Should I downgrade to 9.3?
