Pickilie

I was busy and away from computer but when i came back my computer had crashed.I restarted it and got back on attack of the b-team and the server i play on crashes my technic launcher everytime i try to enter it. I tried everything but still nothing works. Any ideas how to fix this? It is version 1.0.12 in crash report it says that map writer and tropicraft are likely involved files and mods.
