I probably just exported something wrong somewhere along the line.



Haven't had a chance to try this out...but looking quick at there website I could make a good guess as to the problem with animation in your attempt:
Vertices can be affected by up to 4 bones
Chances are good that they wanted to show off that feature in their example models. Problem is that 3DGS only supports 1 bone per vert. Anymore on any vert and the entire animation set is scrapp (common mistake I see with Max exports)...

Double check that and you might find that path working.
