My Game won't start

Each time i start Rust the game won’t work (https://www.dropbox.com/s/omhg7e8t3jc5bqo/Rust.JPG) then the game crashes after about 30 seconds. I Have tried changing the resolution, windowed or full screen and the quality of the game but nothing works, can you please help me fix this. Thanks
