warblender problems

i am using blender 2.46 and warblender0.2.0 (a warcraft3 filetype plugin)
and after installing(moving) the right files to the right directories i get a python(2.5) error
when i click on the “import warblender file” button.

ImportError: No module named Bone
Traceback (most recent call last):
 File "<string>", line 12, in <module>
 File ".../.blender\scripts\warblender\importer.py", line 6, in <module>
from Blender.Armature.Bone import SKINNABLE, UNSKINNABLE

maybe someone got experience or knowledge about that plugin or python and knows how i can get it working?

nobody knows something about that?
