Yes all turns are saved automatically, here is the procedure:
Open the following game directory: Ageod American civil war\ACW\Saves. The list of folders is the list of the games you have on your computer. Select the one with the problem (if you are unsure of the name, the time stamp can help you), then do a right click: you should have a menu to zip it into an archive, as a single file. Zip the game, and then send it by mail if under 5 Mb, or by a website* if bigger (there should be only one file to send).
*sending by a website: you can try
