I just purchased the Kursk expansion and installed it,..but it appears that I can't join any pre-existing MP games where the Kursk expansion was needed.
Is this a chicken-egg thing,...meaning,...MP games existing before I installed the expansion are "locked" to me.
But if a new Kursk MP game were created, then I could join it?

Seems I can't create a Kursk MP game either. Hmmm,...I suppose I'll open an issue with support.

Got it figured out,...even though the install of the Kursk expansion initially asks for the license key.
I had to go into the Campaigns, and select one of the Kursk Campaigns,..at that point it asked for the license key (yet again).
That did the trick.
