I was just flying around and crashed. Now I can't join the server.

[Shadic6]

I was flying around in bat form on a server that I have been playing on for a while and I saw a strange building in the sky. It was built around one of the slime islands from buildcraft but it had vines and lava going all the way to the ground. When I got close to the building I crashed and now every time I try to join that server I crash again. I tried allocating more memory and lowering all of my video settings to see if it was a memory problem but it didn't work.  I have 2 of the crash reports pasted below.
