Ogre XML exporter help.

when I try to export to ogre xml It says: Python Script error.
I have installed Python24 but Im not sure what to do.

Any suggestions?

Please look at the console for a more detailed error description. If you use Blender 2.40, be sure to use the CVS version of the Ogre exporter (see the news on the Ogre website about Blender 2.40 support).
