Within Steam: Library -> Garry's Mod -> Right Click -> Properties -> Local Files -> 'Verify Integrity of Game Cache' Try adding the following lines to the bottom of your garry's mod config file, located at Steam\steamapps\\garrysmod\garrysmod\cfg\config.cfg: cl_allowdownload 1 Make sure Options -> Multiplayer -> Download Custom Content is set to Allow All Custom Files From Server You need to disable all your addons, before starting up the server. Try disabling your firewall/antivirus, or possibly other non-essential programs/services running.

Then verify your cache again.Īs a last resort, uninstall Garry's Mod completely and delete the garrysmod folder (which you'll have to do by hand, because there will be leftover files), then reinstall.
