Even though I am using the newest version, I cannot play. Two minutes or so after logging in my client crashes

Anyone have any suggestions? It seems the fact my Minecraft stops isn't answered in the console log... but how does one go about troubleshooting this? It was fine in 8.0.1.... the only other difference to the server was newest version of Mystcraft... but it was only installed an hour or so ago, surely noone on the server could have made things that quickly.
