Merge animation + blitzkreig = random export module phail?

[Inferno]

ok.. i have no idea why but im getting pretty much random export module fails. some times they work sometimes they dont. theres not patern from what i can tell besides that the merge animation tool in max may be doing something to the animations so they wont export. but its weird cause it only sometimes meses them up it normally works fine....

can someone give me a little help with this... or maybe a list of the things that get export module fails?

Export module failure = frame gun is not linked to frame bone 24/there is more than one parent node (there should be only one).

well thats not either of the problems. the animations export fine UNTIL i use animation merge function in 3ds max. idk why but it messes up after that.
