Model Problem

[Hell_Raider]

I have made a model in the XSI mod program of a pelican drop ship (very low polly), I have then exported it as an OBJ and converted it to an MDX (using the converter from this site)

However when I import in into the game as a new model it makes it look like the alien ship from threshold (has points going out in every direction looks nothing like the model and is continuesly changing until the game crashed).

I figure I am probably doing a nooby mistake... so any suggestions? I am happy to send the model if thats what needs to be done to fix it...

Here is an ingame screen shot of it in the model program

here is it in game

I don't know if this is at your programm to, but in GMAX you have convert all to editable mesh to make it work properly. Maybe this could be your mistake? ???
