Default Alice error on playback - 10-13-2006, 09:54 PM

I'm getting really frustrated here. I've been creating a pretty elaborate Alice project for a while, and suddenly it stops working. When I click play, it immediately gives me two errors in a row: Error during simulation, and Error during playback. The annoying thing is that I have tried to debug it by deleting EVERYTHING in the world. I've deleted all my objects, all my code, everything. It STILL gives me an error. It only happens with this world. So I've come to question the world statistics. Under world statistics at the bottom of the program, "face count" is all in red. and gives me a number around 77,000. I think that's bad. However, when I start deleting things, it doesn't go down. Nor does the objects counter in the statistics. I would think my computer can handle it. It's pretty fast: PowerMac G5 with 1.5Gb of RAM.
Anyway, here is the error output:

Error during simulation.

Alice version: 2.0.7 Mac OS X
os.version: 10.4.8
os.arch: ppc Java HotSpot(TM) Client VM
java.vm.version: 1.4.2-54
user.dir: /Applications/

Thanks for any help
