try deleting the cr2 and importing the obj again as an obj, then adding to library and then , shuitting poser down first, pulling in from cr2. if no error then was simply a corrupted cr2. will have to add the ik data to be able to pose the model, but then you can c&p from original models cr2 the mesh change you made might cause this with the cr2. it shouldn't but it is possible.
