I have a macbook (the old kind, not a macbook pro or air) and whenever I try to launch Attack of the B-Team, it loads the stuff, momentarily opens the window for the pack, and then closes it immediatly after. What am I doing wrong/How can I fix it? (P.S. this only happened after the last one or two updates. I used to be able to play it just fine...) Please help because this is a great modpack and I really want to play it. Thanks
