Normal open launcher but main game opening always crashes.

Minecraft's launcher would open like normal but when I would click play game it would load to the main screen then automatically crash. Every. Single. Time.

I had hoped that if I deleted Minecraft and reinstalled it, it wouldn't have a problem anymore. Note: I bought the game myself with hard earned money. I deleted the game (not my account) and went back to minecraft.net.

It wouldn't let me redownload my ALREADY PURCHASED game. I thought that it might be that I wasn't logged into my account but I logged in and it still said I have to re-buy the game to download it.
