Everytime I open minecraft it doesnt even load to the main menu and crashes.

What i expected to happen was to download the paid for minecraft server and click it and start playing.

What actually happened is i played on it for a day but then tryed to go on it the next day and play it and it kept crashing before the main menu even pops up. I tried deleting it and downloading a new one and the same thing happened.

How to activate this bug is easy... try to open it and it crashes.
