After 3 days I managed to get this to work!
No idea how. Just logged on to Steam and it did another download and intead of spinning sea, I got a play menu !
It's pretty good actually.
I don't know whether my experience is tainted by 3 days of frustration, but it's actually pretty good. Maybe it is just tainted by the fact that it now works. But some fine ships and boats there can be no doubt......
Don't have a clue how to access this alleged radar though................
