Disconnect: Kicked by Console : "Mismatch: weapons\gmod_tool\stools\lamp.lua".

Every time I try to join a certain server I get kicked with this
Disconnect: Kicked by Console : “Mismatch: weapons\gmod_tool\stools\lamp.lua”.

I’ve searched and tried to find a solution to my problem but I can’t find one. Could someone please help?

Update your gmod/stop pirating it/delete any really ancient mods (like Hunts Mod for example) as they may be editing the tool.

None of that worked.

Got it to work. All I did was delete lamp.lua and rejoin the server.
