I em playing FTB for about a month now and newer had problems but now that i updated my Mindcrack pack to 8.2.0 every time i try to join my server that i em running on my computer it starts out perfect but then after about 3 secs of working it just freezes and i have to restart my mac. And when i tried to lunch a new singleplayer world just to see if there is a problem whit my server it doesn't want to lunch and it just says "Shutting down internal server" and then freezes. Can someone please help me?
