when you try to mod animations and you don\'t know what you\'re doing...

About this image

aaaanyways heres what I did (3ds max):
-Took the skeleton from another game
-Transformed it so it oriented the same way as the skyrim skeleton
-Imported animations from the other game
-Renamed the bones from the other game skeleton into bone names of the skyrim skeleton
-Redid the hiearchy of the other game skeleton (at this point there are more bones on the skyrim skeleton than the other game one)
-Selected all bones on other game skeleton and went File->Save Animation
-Selected all bones on skyrim skeleton ->Load Animation
-This happens :(

If anyone can tell me how to fix it please do
