patch to make it work

The attached patch will make the game load files and run. I'm not sure if it's
correct or not, the main problem is that ofn->lpstrFile is NULL so the
functions PathFindFileNameA and PathFindExtensionA also return NULL. I don't
know how it ended up being NULL which is probably the cause of the bug.
