What were you doing last time you managed to be on the server? (if you have never joined, say so)
The last time I managed to get on the server, I was hunting for ghasts in the nether, my tier II jetpack died, I fell in lava, I died, and crashed. I haven't been able to join the server without crashing since.

now that I think about it, I did change my java settings before this, but before they were changed, I couldn't even open the pack. Just in case this helps.
