So i was messing around on my friends server with minetweak to fix some recipes that overlap in chat, and i unknowingly sent 10000+ messages into my own chat, so now when i try and connect it attempts to load these and crashes my connection. is there a way to fix this?

three different versions of Ars Magica II

Im having the issue where when I attempt to start a modpack, the launcher will disappear as if to start the game but then load back up and no game in sight. Running windows 10 log attached crash-2014-08-25_08.40.41-client.txt
