Hello guys, I create this thread in order to have some answers. I downloaded the new launcher. I was on the red server and i try now to connect on the silver one. When i try to connect, it says that my password is invalid. So I decided to connect on the forum in order to check and there are now errors. I changed it and try again. And it failed again. I'm really sorry about this, i think there are some answers on the forum but i can't find them. Thank you really much.
