Black screen in game and level editor o.O

[TheZhadowRider]

So I was lunching my level editor yesterday and it worked fine... but after a reboot of my pc... It just gave me a black screen and the game it self goes black and it just stays black nothing else but when I click any where in the hole black screen its not responding...

I have tried:
Restore windows to a day earlier: did not work
Reinstalled the game: did not work
Downloaded drivers from other threads and advice of this issue: did not work

I think I have tried everything and thats why am asking on the forum if there are any last ideas...

|Other Info|
* The game is on Steam.
*I am running windows 10 on an laptop with GeForce GTX880M and Intel® Core™ i7-4710MQ @ 2.50 Hz and 16 GB RAM.
*And am running the highest settings as possible in game.

Thx
