Cant load screen up to where we can access worlds

Hi, 

I tried to open the game to play minecraft for the first time in a couple months and it comes up to a white screen with the word "minecraft " and a wierd loading bar at the bottom. The problem is that the game will not load beyond that point. Ive tried uninstalling and reinstalling the game, and force closing it but nothing seems to be working. Please fix this so i can play the game. Below is attached the white screen i talked about.
