A black icon on the CyberCafePro Desktop usually means the connection is either not active or it has changed.
Often when a router flakes out or a new piece of hardware on your network is added, you will find the connections for CyberCafePro no longer work. Why? The answer is because the connection parameters were saved in CCP and now they are different. The connections are looking for the old setting and Client info when they no longer exist.
