Might be a gamsspy problem for you.
They maintain the account servers and the server list.
When you first start the game let it update all the servers.
You should see 5000 plus servers.
Make sure you have no filters installed then put ECGN in
the server name, it should show 11 servers.
let us know if that helps.
Just to be safe I checked your cd-hash, its not in the ban
list. Major_Hazard
