CoD:BO GUID...

So, trying to join team in CoD:BO ladder and have entered both Steam ID's as directed and when I enter the join password I get a message stating that I must have a GUID entered for this game. I cannot find any mention or anywhere to enter a GUID for CoD:BO; only the Steam ID's.

Am I missing something?

The issue is that you have two STEAM_IDs, rather than having just one STEAM_ID and one SCID. The 17 digit number needs to go into the SCID identifier slot instead of STEAM_ID. So, you have 0:0:7678523 correctly in the STEAM_ID identifier. You just need to put 76561197975622774 as the SCID identifier. You can see a detailed explanation of how to do this here.

Ah crap, I see what I did; thank you for your help.
