It would be easier to tell you what was wrong if I could see the gmf... it's not just the regular clown head gmf, is it? You must have done something to it.
I THINK it gives you Run-time Error 9 if you have a higher OBJECT_COUNT than you do objects. Try reducing the OBJECT_COUNT (right after the materials and before the GMOBJECTS) until it works.
But it could be something else, like I said it would help seeing the gmf...
