Greetings, Rune Hunters.


Regarding the connection issue currently occurring in certain environments,

a temporary workaround reported by a Rune Hunter has been confirmed, and we would like to share the details.


Please note that the instructions below are a temporary measure,

and the issue will be resolved through an upcoming patch.


◆ Temporary Workaround

1. Right-click the FLOOR Launcher icon on the right side of your taskbar (system tray) and close it completely.

2. Press the Windows (Win) key + R on your keyboard, type %AppData%, and press Enter.

3. In the opened folder, locate and delete the FLOOR, LINEGames, or RzGame folder.

4. Press the Windows (Win) key + R on your keyboard, type %LocalAppData%, and press Enter.

5. In the opened folder, locate and delete the FLOOR or LINEGames folder.


◆ Important Notes

※ Please ensure the setting remains on Shader 5.0 under Settings > Graphics Options.

※ Switching this option to Shader 3.1 will cause the connection issue to recur.


We sincerely apologize for any inconvenience caused.

We will do our utmost to resolve the issue as quickly as possible.


Thank you.
