Hello,
This is the Gravity Co., Ltd. Ragnarok Zero Operations Team.
After the regular maintenance on Wednesday, 6/27, we confirmed an issue on some PCs where players were unable to log in to Ragnarok Zero due to a problem related to the Setup configuration file.
We have reported this issue to the person in charge, and the client patch has now been completed.
If you were unable to log in due to this issue, please proceed to log in after receiving the client patch.
We apologize for the inconvenience this may have caused.
Thank you.
Gravity Co., Ltd. Ragnarok Zero Operations Team
