Me? Just someone who once played the old version of Disco, not an active forum member though, just an active freelancer around Liberty and Gallia that was finally killed when doing a job as a mercenary bomber for the Navy.
If my memory served me right, i think the last version of Disco that i played was, 4.85 maybe? It was about a year ago i think.
Same thing happened with my install, where it would crash after hanging on the splash screen.
I'm afraid the only way that I can say is a complete uninstall of discovery, uninstall Freelancer, install Freelancer DIRECTLY to the /Program Files/ directory and not underneath Microsoft Games, and then install Discovery in its default location in AppData.
