What software are you using to make the 3d models?
Bone based anim only works with DBPRO.
Some 3d modeling software such as 3ds max have a animation sample rate which is sometimes set to 30. (so if the number of frames in the anim is 30 then when you export it the no of frames will become 900)
To fix this problem set the animation sampling rate to 1.
Ur code might be wrong too so post it up and the nice people in the forums will help solve ur probs
