So there I was quite happily playing the 2004 campaign (1.09) last night.
Woke up this morning and Steam downloads the latest update (1.15) and now I cannot get ANY campaign to work, screen goes blank either when, I start an new campaign and select a boat to command or if I go into a running campaign and click to load an autosave.......



Have just tried uninstalling and reinstalling via steam and get the same result.
I am sure you on you guys will have the answer.
