Your scaling needs to be adjusted from MAX to MED, dont know what the ratio is as I dont use MAX but if you were to pull the model in game, it would be huge.
A7 has some issues yet with bones and jcl is currently looking into the prob.
Mostly it has to do with bbones to vertex assignments.
If you have A6, use that for the meantime, if not, maybe you could download it off the downloads page and use your key to unlock it then do your bone work with that MED version.
