Wire Facer problem

I don’t know if I did something wrong, but my wire facer tool wont “spawn” properly. It DOES spawn, but it gives me a lua error, and wont let me adv duplicate it. I’ve tried every wire facer download i could find on garrysmod.org, but it still gives me the same problem.

Use SVN to get the latest version of UWSVN (Unofficial Wiremod SVN, or Wire Extras), which has the wire facer.
