Whenever I try to open the my minecraft game via the launcher, the launcher loads, disappears, then reappears, and says "GAME CRASH: An unexpected issue occurred and the game has crashed. We're sorry for the inconvenience." And no matter what I try I can't get it to run. I am using windows 7. Please help.
