My Minecraft keeps crashing when I launch it. It stays at the red Mojang screen and the loading bar goes up until there is an 8th of it unloaded then pauses and doesn't let me do anything or just straight up crashes. I bought the game 3 days ago and have played it once for about an hour then it crashed and never let me back on. Its also in full screen so it doesn't let me go out of it to try the task manager trick or anything.
