L2J Server

Well i got the following problem.
I am putting the IP at Host (local on 127.0.0.1),opening the L2 and when i am trying to connect i get "Your username and password does not match.Please try login later"
The strange thing is that that happened suddenly.I hadnt changed anything just tried to login and b00m i am not more able to connect.
I tried also to connect at a friends server but same thing.
Tried to turn down the Firewall,reinstall the System folder but nothing worked.
I am using Rooter but i dont believe it matters because:
1)When i am trying to connect on my server i dont need to have the ports open because it is in local (127.0.0.1)
2)When i am trying to connect at my friends server he has the ports open and to connect at an outer server i dont need Ports opened.
And the strange is that some hours ago (12 more or less) i was also able to connect at my friends server

Cant think anything else....

I've got the same. Seems the login is case sensitive, make sur capslock is not enable. It seems also it does that if you enter the login too fast after you got the windows to login (cursor in username is blinking fast then slower, enter it when it's slow).

From time to time it doesn't work and checking the db, the password is good. No idea why. Seems more to be a server issue than a datapack issue anyway. You should try the L2J board.
