Adobe LiveCycle Designer 8.2 ES keeps crashing at Startup

I've upgraded from Adobe Acrobat Professional 7.0 to Adobe Acrobat Pro 9.0. Acrobat works fine. However, every time I launch Designer I get a debug window at the splash screen. The program freezes and quits everytime. I've repaired, uninstalled, and rebooted several times. 7.0 is completely uninstalled. I've even checked the registry. Still it freezes and crashes.

I'm on XP SP2 and have .NET Frameworks 1.1, 2.0, 3.0 and all their SPs.

Please help.
