Mesh export error - MeshSerializer

Hi,
I am running through the tutorial I downloaded from this page: http://www.ogre3d.org/tikiwiki/tiki-index.php?page=Mogre+Wiki+Tutorial+Framework
When I try to add my own mesh created in blender 2.70a and using blender2orge 0.5.8, I get the below error:

OGRE EXCEPTION(7:InternalErrorException): Cannot find serializer implementation for current version [MeshSerializer_v1.8] in MeshSerializer::importMesh at ..\..\ogre\OgreMain\src\OgreMeshSerializer.cpp (line 118)

Am I right in thinking that I am exporting a newer format mesh to an older version of ogre? If so how do I get round this?

Thanks

Yes, i meet the same error, when you use ogitor 0.5.4, it based on ogre v1.8, but mogre currently build based on ogre v1.7, so it will notice error. There are two way to slove this error:
1.abandon ogitor, build scene manually
2. download ogitor source code, and build it with ogre 1.7

hope can help you

or you can build mogre 1.8 version

or you can download ogitor compatible with ogre 1.7(i have tried, is ogitor 044)
