if you still get the error after mounting the track at the top of the pod.ini like Phin suggested then it's a corrupted model in the track causing the prob, normaly you'll get a portion of the models name in the error instead of the NULL but sometimes ya don't...
Do you know which model it might be? if not I'd try removing models from the track one by one in reverse order that you put em in to determine which one it is by creating a new pod and testing after each change.
once you nail which model is crashing the track then load it into binedit and hit Ctrl+A to select all the faces then click the "Groups" drop down menu, then click "Set Group Face Type" select "0x29 Shiney Texture (MTM2)" from the list, click OK then save the bin. place the newly saved bin in your traxx models folder and give it a try...
NOTE: if it's a tree or other transparent type model then select "0x33 Transparent Color #0 (MTM2)" from the face type list.
it should work fine now, if not zip up the model and art and send it to
binrepairshop@malibu350.com and I'll have one of the boys put it up on the rack and take a look, no charge.
