You can no longer update the v1.3 from Steam to the v1.4 patch from Ubisoft. It will mess up your Steam license and not run. Just put the v1.4 Silent Hunter: Wolves of the Pacific U-Boats Missions on top of the v1.3 install. I think that the Steam installer defaults to that anyway, ~IF~ I'm remembering correctly... Use Steam's download manager though, and don't put them in the Windows folders. Have Steam make you a different folder to put it in... They used to say on the game page for UBoats Missions that it "required" Wolves of the Pacific... Like it does if you click on an add-on for the IL-2 planes game... hmmm...
Does the UBoats Missions from Steam now "stand-alone", does anybody know?... That'd make it like the "Gold Edition" on DVD if it does...
-NEVERMIND- they moved it down a little bit, and it's no longer up by the "Buy" button...
- to be expected... this quote is now down in the "body" of the text:
This is an expansion for Silent Hunter: Wolves of the Pacific and requires the Steam version of the original game to play.
