.blend to .xml?

I’m not sure if I am asking this question correctly, but I’ve been tasked by the Creator to convert .blend files to compatible OGRE formats. This is difficult for me because I don’t even know what to do to get OGRE running (Zero programming skills). If I don’t get the files converted, the Creator will smite me, so please help me get this thing going? Thanks.

I’m using Blender 2,5 .blend files.

Don’t know if it still works with any current builds but worth a try
