No, I'm saying that it is my belief something from the Unofficial wire extras pack is breaking your toolgun.
Nothing to do with UPS..just that I saw the extras pack break stuff before.
Make sure you have latest SVN of all wire related packs...garry made an update recently that broke wiremod..it's likely it broke the extras pack too. Wire team fixed thier code...did the unofficial wire extras team?
You should research that, if not, try removing the wire extras pack.
