• Privileges set  BUILD 1479 SERVER (0 CRC) Server # 196 Server is running game ag. Restart in that game to connect.

seems like you dont have ag, download it in openag.pro download full mod package and extract it and put the folder you extracted (folder name is ag) in your steam half-life directory so in steamapps\common\Half-Life now restart steam and you should have a game in your library called openag which you can connect to the server from :)

ahh i understand. I was installing it in the valve folder :D thanks man
