FTB Crashing when logging onto a server for a little bit?

[WinBillion20]

Hey FTBers I've been playing FTB a lot but for the first time today, I have noticed that when I long onto this FTB server that I play on almost everyday, that I crash after about 10 seconds. I have tried playing with my quality settings, changing process priority, and upping the ram usage but nothing seems to work. Heres the crash report, hope someone can help!

Try force updating (options tab). If that doesn't work ask someone else to remove the traincraft assembly table III that is nearest to where you spawn, they may need to simply replace it or remove it entirely.
