Ok, I haven't used this for a while so I'm stumped, in finding the problem in my code... Every time I try and run the code, I get a "memory access violation". If any one can help I would be most thankful. I also am going to change the code to a more FPS format but I have to find this error first, THANKS! here is the code...

Turn debug on and you'll probably get a more descriptive message. You cannot expect anyone to find the issue when they don't have all the media. It could be anything, missing textures , missing meshes etc..

Maybe because you're not loading the mesh files, several paths have 2 \ chars in them eg. "guns\\w_fiveseven.3ds"
