Problem importing files with blender 2.49b and Unity 3.3.0f4

When I try to import a .blend (2.49b) for the Unity (3.3.0f4), there is unity displays an error message saying that it was not possible to convert .fbx.

I reinstalled the Unity and Blender also deleted the files from Regedit and has not worked.

Anyone have any idea what could be the problem?

thanks

Well, I don’t know why you’re still using Blender 2.49b, first of all, but the easiest way to export from blender would be to go to

File → Export → Autodesk FBX

then it saves the .fbx format of the meshes you selected, and you import that into unity. If it doesn’t work, play around with the .fbx settings in blender.
