Can't sign in because of "game crash"

So i just got my minecraft working again and now, a few days later, it's getting to the Mojang loading screen with the red bar, not loading all the way and i click a couple times and it says "Java(TM) Platform SE binary is not responding" then i get an option to wait or close the program. A couple seconds later, I get an "ERROR Game Crash An unexpected issue occurred and the game has crashed. We're sorry for the inconvenience." and i get an option to close or View crash report, but it will not let me view the crash report. I have tried uninstalling it but it hasn't worked, to try to fix it, i got to minecraft.net and the home page says "Buy minecraft" and i have already bought minecraft.
