Make sure to put your topics in the right section.
Console returning "Unknown command "meta"" instead of "meta version" is not a problem. That's just simply saying metamod is not loading for some reason. If you have all the files in the correct place, the problem probably is that metamod.vdf is not pointing to the correct directory. You can open it up using notepad and see what it says. Mine says:
Code:
"Plugin"
{
"file" "../zps/addons/metamod/bin/server"
}
Which is probably what yours already says, if not change it, save it and try again. Make sure that metamod.vdf IS placed in "../zps/addons/" and NOT in "../zps/addons/metamod/".
