I've just downloaded the full game onto a Windows 10 laptop and starting multiplayer and skirmish both seem to work fine but when I click play offline, the screen looks like it's changing resolution or something and goes black like it's loading but then the screen goes back to normal and nothing happens, with no error message.
There are a few things already on here that looked like similar problems but they all had error messages and, to be honest, I didn't really understand the answers; please help
Cheers.
