My USGN don´t work on CS2D update! Why?

You mean that your account can't connect to the U.S.G.N.?
If that occurs, try follow the following link to solve the issue. If that doesn't help report back here.

Net Login (FAQ)

The problem is: i can login sussesfly but in-game don ´t works.

That's quite a odd problem. I have never experienced such before ever. I'm afraid that your problem is unique at least from my knowledge.

Because if you're able to login there shouldn't be any problems. Maybe it's your connection which is slow, or you may have port problems. Try port forwarding the CS2D port 36963 on both TCP/UDP in your router and see if it works.

Same. Especially when you change anything in the options.
Sometimes it helps to restart the computer.

Still have this problem...
Any suggestion?
Can't play for a 1-2 weeks,because of dat.

The FAQ - KimKat already gave the link - covers all known problems/solutions about that.

@ DC: Well,i can't find exactly my problem in this list.
I'll try to describe dat:(Used already 4-5 different cs2d folders)
I entered the game -> setting -> net
Put my login and pass data(yes,i used right data)(yes,i tried again)(yes,i know that you have brute block,and waited for 15min then again 15 to try again,nothing happens)
When i done,i pressed okay.
And nothing happens,just "-".(as i understand it is brute defense,but i logged after night of rest)(yes,i am sure that nobody didn't use my pc every 15 min before i logged :P)
So you still don't know how to fix that?

Doesn't look like you did everything on the list. Please go through it from top to bottom without skipping anything (IMPORTANT!). Note that I just edited/optimized the list a bit but the content is basically the same as before.

And no, I can't help if this list doesn't help because I put EVERYTHING I know about login problems into that list so people can solve all known problems themselves with it.

Edit: Oh, the thing should say "trying to login" a "-" means that no login data is specified. Maybe you are using a folder without file write acces (e.g.: C:\program files). Make sure that CS2D has the permission to access files. Maybe run as admin.

@DC
When there are 20+ symbols in password,what does it mean?
It seems progress because now i have "trying to login".

That your password file is probably fucked up. Remove it as described in http://www.cs2d.com/faq.php?show=net_login#net_login under the heading "Password file somehow damaged - remove it".

Try the part "Nothing helps? Logout and try to change your password!" if you still can't login afterwards.

Well , sometimes the USGN doesn't work.
Change your password , relaunch the game. If it doesn't work.
Try to delete the whole game and download it again.

P.S : Sometimes , you see yourself online in the game otherwise you're not you can remark that by checking your USGN in the game by saying rank and this problem is always
happening after joining the editor.

Your problem same as me, it caused ur router slow and ur router cant port. The last solution is not playing using usgn

Open ur console
Put in:
usgn_user "name"
usgn_pw "password"
If you want to connect to another server you should do the same thing all over again.

i done as zet said,and now it works!
Contratz to zet!
