Sometimes bugs and login errors you may encounter may be due to corrupt game files or a client sided issue. You can quickly perform what we call a "repair installation" on your game to repair or obtain any missing files.
If you are launching your game through STEAM:
- Open up your Steam Library
- Right click on "Mabinogi" and click "Properties"
- In Properties, click on the "Local Files" tab.
- To perform the repair installation, click "Verify Integrity of Game Files..."
- Once clicked, the validation process will begin and any missing files will be reacquired! ヽ(^◇^*)/
