I uninstalled and reinstalled my Garry's Mod to fix a texture problem, which updated it to Update 165. There were only a few servers in each gamemode on the multiplayer server list. And whenever I tried to join one of the servers I frequent on, they gave the error, "This server is running an older version of the game."

So then I went on here, and saw that everyone is having trouble updating itself. But does anyone know how to downgrade Garry's Mod to 164? There is literally only like...13 TTT servers, 1 Jailbreak server...something like 50 Sandbox ones. The problem is many server owners are having trouble with mounting CS:S onto their servers, another side effect of Steampipe.
