I’ve got the same thing.
I’m on Win7x64 and using CS4.
Upon closing AE, I get a crash dialog concerning “ae.blitpipe” (no idea what that is) but my project is not harmed.
I did get a few errors when starting CS4’s Photoshop recently concerning my Video Drivers not activating something….hmmm. I’ll have to look into these apparent connections here with my Video Card.
I hope we can all get to the bottom of this soon! 🙂
