I’ve opened up a Mabinogi application entry here, since no one else has done it. Either Mabinogi has to be working properly, or GameGuard needs to start working:

Please take the time to register and vote for GameGuard or Mabinogi support in Wine; GameGuard moreso.
P.S. Mabinogi in the above link may take time to be approved before appearing.
