Me and my friends play on a server together that i host, but one of my friends minecraft wont launch all of a sudden. when using forge 1.7.2 forge 10.12.2.1147. so he can get to the launcher, and when he hits play the launcher goes away and nothing loads, and theres nothing in the task manager. but as soon as he takes off forge and plays on default MC it will launch and work. we have tried it with mods, without the mods, re installed forge, different forge versions. im out of ideas. it was all working fine a week ago and he says he hasnt changed anything. it just all of a sudden wont launch. any help?
