UPDATE...
Hi, just sorted it all out (I THINK).
Turns out it was the 3D model after all that, something was wrong somewhere, But the game i had problems with works fine now.
Anyways doing a clean re-install i got rid of some of the M$ crap on the computer.
I took the model right down to the basics and left just the left hand side, deleted all the construction history i had (I couldn`t delete it before as i had a bone/skin setup) and deleted anything i didn`t need anymore.
I`ve just gotta put it all back together again and i`ll have a update picture maybe next day or so.

UPDATE...
Sorry i havn`t been in much over the week, i hope to get back to modeling soon as possible.
