Today went to the cs of 2D, and was not able to enter under usgn. + Cannot find server. Reinstalled cs - and the same problem. But I can play on the servers that I have in my favorites.

try turn'off your firewall, that will get ride of your problem

But I hadn't turned it on.

well that's strange, oh i remember a thing, if u use wifi connection(like me) i'ts petty normal that problem, you can try disconnect and re-connect the wifi...

The Windows firewall is on by default.

DC will have to fix this issue... Log-in doesn't work, neither does the server list.

We'll have to wait til he sorts this out.

I have portWAN, and have cable connection.
"try turn'off your firewall, that will get ride of your problem"
Did not help
"The Windows firewall is on by default."
Yes, but I turned it off after installation of Windows.

huh... well, can be useless, but download again the game, try they 2 versions, .exe and .zip, if non of then work yet, the last thing you can do is try play in another computer, if the problems persist, it's ur internet.

no.
my too i have it.
about join server you can but you need wait same time
and usgn all have this probleme.

I'm having this problem too, was playing last night and then bam, disconnected from server and unable to connect to U.S.G.N.

@ CaneCorso:

That's true, the master server will be down for a while. You just have to be patient until DC restarts it, however I can suggest you to use my U.S.G.N. id recording system ( U.S.G.N [OFFLINE SERVICE] (9)) when the master server is online, this will bind your IP to your id if you're playing on your server.

The topic points isn't clear but I can see that your U.S.G.N don't work.
Well , you should wait. I had this problem before , waiting is the solution no one will help you.
