Hi, I registered my alt account a couple of days ago, but when I tried to log in today, the system showed the message: “This is not a registered ID.” Could it be because I linked my alt account to the same email address as my main account? If that’s the case, I can provide a different email address as a replacement. For reference, my IGN(s): CorallBaay, Coralbucc.
Nah, the email addresses aren't the problem. There is a very high chance that you are not typing your username correctly. You can recover this in a support request, but it will take awhile. I would recommend having a look in your web browsers/password managers remembered usernames and passwords to see if when you created the accounts, you auto-saved them. Also keep in mind that it's the username you put on the account, and not your IGN, that you need to use to sign in.
Ahh, you’re absolutely right, I mixed up the username. That was my mistake. Thanks a lot for the clarification and your help! You can go ahead and close this thread now. Appreciate it!
