I've had a problem that seems to be pretty common. I downloaded AOTBT just fine. When I hit play, the launcher disappears like the game is starting. Some times the "FML is setting up your environment" "CB Deploader is setting up your environment" message comes up. Then the launcher comes up again, like the game has crashed, but there's no crash report. I've checked multiple times. I went through the mods one by one, and it seems that open blocks and open mods aren't working right with project red. Also, tropicraft isn't working right with something. The java updater says I have the newest version of java, and I have reinstalled both AOTBT and Technic Launcher multiple times. My friend plays AOTBT on Windows 8 (I'm on Windows 7) and he has no problem at all. Does anyone have any ideas?
