FMRTE freezes when I open it

Hi, until a couple of days ago FMRTE works fine on my PC, but now, when i try to open the program it freez (white screen). I've tried to reinstal and also I've tried to install an old version but is happening the same. I have Windos7. Any ideea?

Sounds weird to me.
If it was working fine a couple of days ago and now even using an older FMRTE version it freezes... there's something about a change on your PC that might have caused the issue.
Everything fine with the NET Framework?

i didn't chanche anything on my PC, especially on NET Framework. Anyway I've tried to reinstall also the freamwork, and nothing

is it only fmrte that makes your pc crash or is there anything else that does the same?

only FMRTE
