❌ Client Crashes & Error Messages

mfc100.dll missing

• Ensure you are using a clean, updated Ragnarok Online base folder before applying our server files.

🖥️ Display & Resolution Issues

Q: The game screen is too small, or I get a "Failed to Set Graphic Device" error.

A: Your graphics settings or screen resolution need adjustment via the setup utility. Open your game folder and right-click on opensetup.exe or setup.exe, then select "Run as Administrator". Inside the setup panel, choose your primary Graphic Device from the dropdown menu (instead of leaving it blank). Adjust the resolution to match your monitor's display settings, and ensure "Full Screen" or "Windowed Mode" is checked according to your preference.

🌐 Connectivity & Login Failures

Q: I am stuck at "Rejected from Server" or "Failed to Connect to Server".

A: This means your client cannot establish a secure link with our hosting nodes. Check your internet connection or try restarting your router. Ensure that your firewall is not blocking the game client's outbound network ports. If the server is undergoing scheduled updates or maintenance, announcements will be posted immediately in our official Discord channels.
