map loading

I downloaded a tutorial from www.gametutorials.com and he used a map file that just contained a list of vertices. His function read the file, counted the vertices and then created polygons with each set of three vertices. The EXE that came with his tutorial worked fine but when i used the function with the way NeHe creates the OpenGL window it compiled fine but the program crashed when i ran it. Is there anyone that i can send my code to who could possibly tell me what i did wrong or could anyone download the tutorial at www.gametutorials.com on Camera World Collision and try to use his map loading code and tell me where i went wrong? Thanks.
