Crash on Open Any Project

This is driving me nuts. Cubase 8 is crashing any time I open any project; even new empty projects. It freezes in a solid white panel where the project window should be. I’ve removed every possible plug-in, I’ve reinstalled Cubase, I’ve uninstalled Cubase and reinstalled. I installed Wavepad to play around with, which is the only change I can think of that I’ve made before the problems started; I uninstalled it and made no difference.

I have Cubase 7 and 7.5 still installed on my system, and both of them work perfectly. I’m at a loss.

Hi! I’ve the same problem with Cudase 8 pro (Win7) And I’m lost too(
Tell me pls how You solved this problem?
