After updating minecraft to version 2.0,760 it chrashes after pressing play button.

Today I updated Minecraft, to the newest version. My little sister wanted to play, but the game crashes all the time, after pressing big "PLAY" button. Then I get notification from windows, that I can close the program, or search for help online, which gives nothing. I tried to repair program few times, by clicking repair option in Minecraft wizard installer. I also downloaded MC-112780 nvidia game driver hotfix, but it didn't help either. For 100+ attempts, I have been able to run the game properly two times.
