Hello. Sorry about that delay. I hadn't received the email, but Mike forwarded it to me. It was the problem I mentioned in my last reply. I will get this fixed in the next plugin build so this isn't necessary in the future, but you can fix the issue immediately by renaming your objects that have characters C3 can't use for object names (like spaces).
For instance if you rename JARI DEPAN to JARI_DEPAN
and JARI BELAKANG to JARI_BELAKANG
