Adv. Dupe is gone

So, because Gmod wasn’t working properly yesterday I decided to do a clean uninstall. Upon re-installing it and downloading the old (and a few new) stuff, I find out that the adv. duplicator no longer shows up in the menu to the right when you press q. In the gmod directory, the files are there. The file called “adv_duplicator” is still there, in data.

Is there any way to make it re-appear in the menu?

Make sure you’re using the latest SVN version of Wiremod (and thus the Adv Duplicator as well).
