Gmod Darkrp "Property Disabled for now" *help*

We recently installed Star Wars Lightsabers (http://steamcommunity.com/sharedfiles/filedetails/?id=111412589 ) on the server for admins just for screwing around and are able to use them from the weapon menu but when we go to right click and “take this lightsaber” it says Property Disabled for now. This also goes for the drive command when pressing c and right clicking something. Please help.
