I have the Windows XP Firewall and my service provider is CNS Cable. Only with this version have I had these problems. About 2 years ago I had a similar problem so I just quit up****** versions then one day I said , "OK, I'll get the new version". Since then a few problems here and there but this thing will sometime connect and then it won't. Also I tried deleting and then downloading the new version. Why does the "LISTEN TO PORT" # change when I do this?
