I was able to connect to any Cod4 server through IP, but now there is a problem. The problem started when I tried to change my GUID, I think. I changed my GUID and now I cannot connect to any Cod4 servers through IP. The ones in "Join Game" all work fine, but I want to play Deathrun... I even tried uninstalling and re-installing Cod4, using a new serial key, and it still says the same thing, "Server Connection Timed Out." Can someone please help me? I've searched and searched but cannot find any working solution. Thank you so much if you can help me.
