while on the subject .. the habware plugin will only work to v5.x of Max not 6, and there are 2 versions .. 1 for v4 and 5, and one for v3 so make sure you get the right one. I also had a problem with models exported with a new UV map .. habware would only output correct uv if I exported as only triangles :( .. it was joining 2 UV coords together or something weird like that.
