You're getting a generic OpenGL crash. Unfortunately, the only thing I can suggest is updating your drivers for you graphics card. If you have an older card, there may be no newer drivers available or there may be necessary workarounds.

well i dont have a graphic card on my pc i guess ill have to buy one soon to play the game properly thanks for the help anyway.
