Hello.
This is the Gravity Co., Ltd. Ragnarok Zero Operations Team.
We would like to provide additional information regarding the issue where, since April 18th, some security programs have been misidentifying the security solution 'Cheat Defender' as a virus.
This issue was reported to the developer (Cheat Defender), and we received a response stating that the developer coordinated with Microsoft and has carried out a related patch.
If you encounter an error message related to 'CDClient.dll',
please delete the client you are currently using and reinstall it before use.
We apologize for any inconvenience this may have caused,
and we will continue striving to make Ragnarok Zero even better.
Thank You.
Gravity Co., Ltd. Ragnarok Zero Operations Team
