Weird Max Art tools problem, please help

I am helping the Star Trek total conversion team with some models and ran into an odd problem. I made this model but when I try to preview it with art tools it crashes max. I tried starting a new file and just importing the geometry with no luck. All my other models preview fine. I am attaching the max file, if anyone knows how to fix this or what I did wrong this time please let me know. Thanks in advance.

Well no one replied, but I got it to work anyway. I still don't know exactly what happened so if anyone knows it may be good to share, what I ended up doing was merging it into a file that was previewing correctly then deleting the elements in theat file and leaving only the merged stuff then resaving it, seems like a bug to me.
