Check the cr2 and find the obj. that it's pointing to. Load a version of the obj. with that name into the same character folder as the cr2. See if the obj. will load. 

As for the non-saving problem, I don't know. Test to see if you can save characters to the Figure library and if the objs. appear for those. If they do, Poser may have decided it doesn't like your obj. Strange things happen sometimes. If nothing saves, try a reinstall.
