Hello,
I'm currently unable to log in to my account i get the message "disconnected from server" shortly after the message "connecting". i went to verify on the website and i'm unable to log in to the website too, i get the message "Login failed! Bad credentials.".
I changed my password, and still not working. doesn't seem an IP Lock problem since it's disabled on my account as far as i know.
Hope, you'll assisst me to solve this, and that it's not a major issue that can be fixed in a short time.
Best regards.
EDIT: I'm able to log in again, thank you.
but i still want your advice to not have this problem another time.
