I downloaded a custom weapon to replace the Colt in COD4. I put all the items into my map and spent time figuring out all the problems, but this one has me stumped.

It refuses to give me the weapon when I use the give command to obtain it.
Using 'developer 1', reveals that it cannot open the view and world model files.
The mod compiles correctly.

Upon opening the models in Xmodelutils, it spits out a message saying it has to use the COD4 setting to open the file because it's a COD4 xmodel.

And unless it's the same porting from BO, I don't know a guide on how to port it.
