So I'm having issues with my Technic Launcher. When I try to play Attack of the B-Team, it loads like it's going to start the game then the launcher disappears. After a couple seconds of nothing happening, the launcher re-loads like nothing happened. There's no B-Team game up. I know a lot of other people are having problems like this with their custom mod packs. This happens to all of my modpacks. I deleted and redownloaded .technic and the launcher but that doesn't seem to help. Also restarted my computer a couple times as well. Does someone know what's going on?
