Hello. We are the SUN Classic team.
It has come to our attention that there is an issue where newly registered accounts are unable to access the game.
This issue occurs when players run the client after logging in to the homepage, and an error occurs on the server selection screen saying that the login information is incorrect.
We are currently in the process of investigating this issue in order to determine its cause and fix it.
We will try our best to solve it as soon as possible, and we will notify you again through this notice once this issue has been fixed.
We are very sorry for the inconvenience caused to our players due to the issue above.
※ September 18th 17:42 fixed it.
