Minecraft Forums

Alright. I'll get to the point. I downloaded mincraft 1.6.2, 1.6.2 forge. You know. Well I open the launcher and up in the corner it has "Versions" which is 1.6.2 and 1.6.2 forge down to 1.1.1. Well 1.6.2 will launch Minecraft fine. but when I try and launch minecraft 1.6.2 forge it starts up. It says Mojang and then the window at the top says "Minecraft 1.6.2 forge (not responding)" and then it just closes.
Ive gotten it to work a couple of times. I don't know how but it ends up being only 1 out every 500 tries. well Ive done the force clean and reupdate. all that I can think of. I'll paste a copy of the most recent crash report if that may help.

This is happening to me as well, but I have not been able to make it work. I suspect it has something to do with the new launcher (1.1.1). Any help with this subject would be greatly appreciated.
