Scourge of War Boards

So I downloaded and installed Pipe Creek and Antietam and Pipe Creek shows up on my Other Battles tab with its scenario but Antietam is nowhere to be found... what should I do? It clearly looks installed by the artwork and the folders but when I am in game I can't find Antietam.

The first question is did you install the 1.4 patch? It has to be installed for Antietam to work correctly.
