there were a number of errors in the model.i did a quick fix just to get it working in fpsc & have sent you the file.
after looking at your model i feel i should give you a few tips on modeling.
your model was made up of lots of primatives all stacked together.this is bad practice as you end up with lots of hidden faces that you dont need ,this adds to the poly count & makes uv mapping harder.
try to start with a single primative then cut or extrude new faces into it ,then move verts & edges to get the shape your after.
after you have the basic model done go over it & make sure you only have tris & quads ,by welding & merging verts & edges.
learn to uvw map there are loads of tuts on the net try youtube.you cant make game models without this skill.it seems like a nightmare when you start to learn it but once you get the hang of it its easy.
for example a model like this can be mapped in about 5 mins (i should know i just did it lol )
i made a copy of your model & uv mapped it using the above tips & have attached it for you to have a play with.take a look how its made & try to make an exact copy of it this will help you with your future models.the uv map is included so you can see how i layed out the uvs,your welcome to texture it & give it away if you wish just give me credit.
mine & yours side by side
uv map
i hope this helps
