Fritzing has suddenly stop working

Hallo,

Have been working with Fritzing the last couple of day’s with no problem.
But suddenly it stop working.
I only get the splash screen and then it disappear. No error or message.
I’m on windows 10 64bit.
I also tried to 32bit with no luck.

I downloaded both again , extract them in new folders just in case but still no luck.
Help.

Update:
i just downloaded 0.8.7b.
0.8.7b run with no problem.
