I am currently playing the 1939 Campaign Storm Over Europe and I am currently in the date July 1945. I was just wondering at what date will the Campaign automatically end. I vaguely remember it maybe sometime in 1946? I am really enjoying playing this Campaign and will be trying other Campaigns soon.

The problem has now been resolved because I downloaded the Community Pack DLC via Steam and all the extra Campaigns appear to be loaded now in Single player mode.

I recently purchased Strategic Command WWII: War in Europe from Steam with the latest patch on it V1.25.00 but it only has the 6 basic Campaigns in Single player. I thought there was extra Campaigns (13 in total) including a WW3 campaign. Any info or help on this would be appreciated.
