Post-update Booting Problems

[BlotCoo]

Ok, I recently ran update and spent a few hours updating Knoppix. When I rebooted, I tried to login and it acted like it was going to do something, but then the screen went blank and the login screen came back on again. I've changed the session type, but nothing, other than the failsafe, works. What is causing this problem, and what can I do to fix it? Thanks for any help!

Uh. Knoppix breaks when you run update.
