I'm finally able to play this game.

You all were instrumental in getting me past some of the hurdles.

Ubisoft provided the clue that told me to disable the proxy setting and that allowed me to log in to U-Play.

And finally a STEAM user supplied the last bit of info...

The advice (Rightclick SH5.exe in the Steam Gamefolder of Silent Hunter 5 then choose Compatibilty Tab then set the X on "Disable scaling on High DPI) worked like a dream. (just for good measure I also ticked the box about "run as admin")

The missing piece! It now runs great (albeit a little slow in loading)
I can FINALLY try this game.

Thanks to all who helped.
