I'm installing this on my new server. I'm too lazy today to put files manually so I just grabbed addons folder from my old server. I updated files with new, delete old ones...Then tried to start a server, but then I got [TF2ITEMS] "GiveNamedItem" offset = 466 and then crashed. And this happens every time when I try to start it! Please help.
Solved!
By defeating my laziness and reinstalling everything manually.
