Adv Duplicator error

http://img338.imageshack.us/img338/6862/gmcyclopean0000.th.jpg

Every time I attempt to paste something out of the adv dupe list, that happens.
Doesn’t matter whatever it is I try to adv dupe.
Everything gives me the same error and only entities seem to appear.

Anyone? This error is very bothering to me due to the fact that I’m unable to paste/spawn/whatever Adv Dupe files.

You could just re-install the addon. Your saved dupe files will be kept safe as they are stored in the data directory.

Make sure you’re getting the SVN version that comes with wire (but you can also get it separately, find the link on the gmod wiki), not a garrysmod.org upload.
