Windows xp crashes when vvvv starting - Help please

Dear friends,
Windows XP crashes when I start vvvv. I am running Windows XP on Bootcamp in a Mac Mini Core 2 Duo P8600 2.4 Ghz. 2Gb Ram.
When I double click vvvv.exe the grey square appears but nothing else, and xp crashes.
I tried to uninstall other software. And I checked the prerequisites.
But the problem persists. Could someone help me please? I am on a hurry.
Waiting for hearing from you. Thanks a lot!

please start vvvv.exe using the
argument. this will create a .log file placed next to vvvv.exe which you could post here to help us help you.
