Collada 1.41 error! help!!!!

Hi, i was watching the new mixamo-blender tutorial that uses the collada 1.41 import script,
I downloaded it but when i run it I get this error:

File “/Users/Daniel/Desktop/3d/Blender/Blender2.49b/Application/”, line 16, in <module>
import Dom4Blender
ImportError: No module named Dom4Blender


The error is probably because you are using the wrong plugin.
We have released a plugin for Windows 32 bit and one for OS X.
They are both linked on our page:

You need to copy the whole folder inside scripts as explained. Note 4.import on the webpage.

Best Regards,
