You have a leaky CoDec on your source footage or similarly an incompatible effect wit ha memory leak. You will need to provide much more info and screenshots of those details.
Thanks for the quick answer, mylenium.
The problem lies in the texture-management of the vc element 3d plugin. So I will report the issue to videocopilot. this can be closed.
There just opened another problem.
I recognized, that the application manager doesn't list after effects.
I'm running on 64bit for sure though (Quad-Core Intel Xeon).
Edit: And I can't install the updates manually. According to the system requirements, it's maybe the officially unsupportet GTX 570? Any other requirement is fulfilleld.

Why not? What happens when you try?
I downloaded the Update Patch "AfterEffectsTrial-11.0.4-mul-AdobeUpdate" and 11.0.1 - 11.0.3 too.
I don't know why there's a "trial" in the Filename, I downloaded it from here: http://www.adobe.com/support/downloads/product.jsp?product=13&platform=Mac
All Patches prompt an Error-Messagebox with german Text.
"Update fehlgeschlagen. Updates konnten nicht angewendet werden. Dieser Patch ist für Sie nicht geeignet."
"Update failed. Updates could not be executed. This patch isn't adequate for you."
Followed by some lines about using the help files or the support-website, with no specific url or any error-details.
