The problem with the OBJ files happend to me too. Only it said on my end, that it could not read the .obj files. If you have that problem than you can solve it with deleting the .rsr files from the geometries directory. If it cannot find them.. look at the settings of the .cr2 file in the character library. Make sure that the .obj files are in the exact same directory list as the rsr files says. Remember the files are case sensitive. I hope this will help you a little. :)
