This has been covered before (my horse for a search function!) GMax is next to useless with DBPro, the only format your likely to get out of GMax is MD3, but this is extremely buggy in DBPro's current state. Best stick to .x using another modeler as DBPro has had a major overhaul regarding .x and .DBO formats. Other formats will be debugged later.
