Engine Crashes on Play

Dear developers,

im using UE4 since few days ago and it was working fine. Right now the program crashes down whenever i hit the button “PLAY”. I have also built a simple game using the basic example (FPS starter content) and execute the game under windows and it crashed down even the compiled program.

It was working fine since few days ago and now stop working, i hadn’t installed any other components so it seems to be a engine issue, how can i solve this?
Thank you very much in advance.
