LINK - Incorrect Password or Login

Personally I do not speak English very well, but we will try =].
I have a question:
Say I have GOD items on the server, but I have the patches required to visualize them. This could cause the connection error ENRE client and server? (LINK-Password or Login Incorrect).

I'm trying to create a server. I did everything as it is in the tutorial: Client and Server 1.3.1 and all other files - graphics excerpt of items GOD - however, when trying to log gives this error login or password incorrect.

What could it be? (Obviously there are a thousand possibilities). I gave up and searched one noticed people with the same problem and managed to solve - but not as posted.

Details: I created an account called Admin, and she is the only one who can play. The others give error password and login. What could it be?

I do not know much ... then, no idea what can cause this. Help me please!

Thank you! =]

Did you change the ip in your client files?

Yes, the servers appear on the client, usually, but not login with the accounts created. Only with that ID Admin, I had spoken earlier. And this account has already come with some chars created. I deleted them and made a new one.

Check your MySQL (Or MSSQL) And make sure that their UID isn't on the Forbid list. It should be it's own table. If it is in there, just delete the UID and then try logging in.

I did not understand, as well Forbid the list?
Could you please post a screen?
