These are the system requirements for Black Tomato Mod:
Windows XP, Vista, or 7 (32 or 64 bit)
Black Ops Ranked Server (Unranked untested and not supported)
RCON and GameServer's control panel access
glogSync must equal 1, this is set automatically on server settings
glogTimeStampInSeconds must equal 1, this is set automatically on startup
playlist_excludeDlc2 must equal 0 to use dlc maps, this is set at startup
This implies that you already have the latest version on your PC and the correct Ranked Server setup. Additionally, the official website of Black Tomato Mod is not available anymore. Their domain expired and it's now showing something else.
