When selecting Single Player, it says to select a slot then click 'Play'

But Play doesn't become highlighted, only 'Back'

This is obviously a Load Game screen but I can't see how to actually start! (Duh!)

(System Win 10 64 bit )

Also, while I am here, where do I find the quick start guide/ control sheet please? Bought from GoG today......

Thanks

Resolved! I needed to type in a user name (Doh!).

Isn't it wonderful what a nights sleep will do for you
