AE CS6 crashes while loading 3D Cameratracker

Hi everybody,

I'm new to this forum, so please excuse me if the question has been asked before.
I made a project that has some camera tracking in it. I used the built in tracker from AE CS6. So far so good. Everything worked fine.
But after closing AE and reopening the project file the program keeps crashing with the following message:
After Effects Error: After Effects crashed while loading the Effect Plugin "3D Cameratracker" (I'm on the german version, so the english translation for this error message is probably a bit different)
After I click OK I get the same message but with "Auto-Color" (don't blame me for using Auto Color, it was late and I was lazy ;))
Then AE crashes.
Luckily I CAN open an automatic Backup of the file, but thats 3 hours older and I don't want to work on the project with the knowledge that all progress is gonna be lost again anyway.

So do you have an idea on how to solve this?

Here are my specs:

Mac OS 10.6.8
After Effects CS6 (11.0.1.12)
2x3.2GHz Quad Core Intel Xeon
32GB RAM
I also used Particular, Optical Flares, Twixtor Pro (Demo) plugins, but they don't (seem to) make problems

thanks in advance

Thanks, unfortunately the Update didn't solve the problem :(
Thanks for the effort though...
