Yeah none of my steam games that i imported via the Steam import wizard are working either. I dont get a error though, just nothing happens. When double clicking one my mouse dissapears but i stay in Launchbox, the startup screen doesnt even show, but is hiding in the taskbar along with the program. I have to head into the mouse settings in order to get my cursor back in order to close the minimized startup screen.
EDIT:
Actually it appears to be all PC games imported via there respective wizards, so Epic, Origin, UPLAY etc.
