My buddy and I missed the Corsair appearance, but in for the consolation prize.
Install the Black Desert Launcher if the game doesn't start.
The launcher will appear if it's installed.
If it doesn't, try to run your downloaded launcher.
1 Run BlackDesert_Installer_NAEU.exe to install the Black Desert launcher.
2 Start the game once installation is complete.
