My game keeps crashing

[cottonbalzz]

my game loads in fine and I can play a single player game but I cannot play on my friends server. Whenever I join it says in the server that I join but then my game just crashes then goes back to the technic launcher. I have tried everything and now I dont know what to do anymore. does anyone have any suggestions?

this is the crash report:

Go to the .technic folder -> modpacks folder -> the modpack you are playing -> follow this path

/saves/mapwriter_mp_worlds/meincraft_apexmc_co__25590

And delete the mapwriter.cfg:1 file, as it is corrupted. This will let you join again.
