Imported .fbx animation causes no animation to appear.

I’m trying to import a .fbx animation from MotionBuilder to Unreal. Whenever I try to do it. I get the error message Imported bone transform is different from original. Please check Output Log to see detail of error. And suddenly the animation isn’t there while both the mesh and the physics of the .fbx file are still there.

I need help deciphering what’s going on. Unfortunately, new users can’t upload files yet.
