Do you have a Skin Deformer as a child of your object and a Weight tag with joints in there on your object? If you SHIFT+Double click on the weight tag, it should bring up the Weights Manager(WM). Click on the mesh name in the WM. Do you see anything other than black?
When you bound your object, did you switch to the bind tab of the character object and then drag your model in there before binding? I've sometimes run into if you don't drag/drop your geo into the bind list, sometimes the character object doesn't bind properly. So if you didn't do that. Try doing that and then see if that fixes it.
