Can't Play After SS 14w27b

I have to stay on SS 14w27b to play the new snap shots. When I am on anything after that, while in the main menu, I cannot click on anything without my screen just showing the brown background of the page. It happens for Single, Multi, Realms, and options.
I always check the new snapshots to see if its fixed but it hasn't been so far. I have to stay at 14w27b.
Please resolve. Thanks.
