Turn off OpenGL in the AE prefs.
thank you for the answer. that solved the crashing problem, could there be a solution that doesnt involve disabling OpenGL? my current video card (GeForce 555m, 3gb) much better than my old NVIDIA 8600m (256mb), but the old one was able to do OpenGL, and apparently my current one cant. why might that be?

You probably won't like this answer: you got lucky with the old card, and your luck has run out.
AE has never supported the full Open GL instruction set. Since AE projects vary wildly in complexity and the combination of effects used, it's always been a toss of the dice if AE would render properly using Open GL acceleration.
I've often written that Adobe employees almost never -- if ever -- use Open GL when they render. I've never been contradicted.
For anyone picking up this thread (it's probably too late for rrebeiz40 by now!) I have come across a simple but apparently very effective tip that has solved the 'OpenGL driver lost connection' issue for many people using various NVIDIA with various Adobe progs (incidentally a lot of these seem to crop up on Dell machines, especially Notebooks).
(It fixed my issue with Premiere Pro CS4 - GeForce GT 555M on Win 7 Ultimate 64-bit, Dell XPSL702X).
It's posted on http://forum-archive.developer.nvidia.com/index.php?showtopic=5331&st=40 (look for the last post, No 50) as follows:
THIS FIX APPEARS TO WORK...found on an Adobe forum
"This issue led me to this fix: go to NVIDIA Control Panel --> Manage 3D Settings --> Global Settings, and switch "Power Management Mode" to "Prefer Maximum Performance" (the default "Adaptive" setting seemed to be the culprit). And that's it! The key here is changing the "Global" setting, as my individual programs were already set to "Prefer Maximum Performance." I can cause the error to reoccur by changing back to "Adaptive."
Otherwise lots more ideas on this site: http://www.instructables.com/id/How-to-Fix...Nvlddmkm-Error/
My PC has been running for 2 days now. I only put the top fix in for now. Feel happier I have more options if need be though.
It worked for me
Thank you, thank you thank you thank you for taking your time to post in this thread that was more or less dead when you found it. Total lifesaver.
How do I open up after effects preferences, dear sir?
They're under the Edit menu, in a category called Preferences, there's a bunch listed: "General...", "Previews...", "Display...", etc.
