Limbs and their positions tend to be messed up with certain exporting methods, there is something like "text", "binary" etc options in the Panda exporter, you should try all of them out, because if i remember correctly there are 3 options there, and only one will give you usable limb structure. Though even if you can detect the limbs in DBPro, it sometimes (i don't have a clue why, really...) loves to detect dozens of them, however there is only 2 in 3DSMax.
Yeah, i hate this part of the development too. This isn't really DBPro's privilege though, every platform has its incredibly time consuming crap.
There exists an other exporter for newer Max versions i haven't tried yet, you should check that out too.
