did a fresh install using this launcher.

no incorrect data found when validating files.

once my installation was complete and validated, I attempted twice to launch the game. This failed, but the process was ongoing in my System Monitor, even though the game hadn't launched and the Experimental Linux Launcher closed after I initiated the client launch.

So I attempted to launch the game client from .../.local/share/ProjectGorgon/HeadlessLinuxPlayer default installation directory. Once again, no visual launch, but the ProjectGorgon process was running.

Lastly, I opened the Properties of the ProjectGorgon executable file and manually designated Wine as the default program to open the file with. No luck there either.

running the latest version of Mint.
