Please explain. We're expected to compress (zip) our save game files?
Yes, you are expected to compress any files that you share with Stardock. You can follow the steps below to do this....

Simply open said program and follow instructions that are included with that program.
(Windows 7)
Open file folder containing the folder with your saved games (only those you are sending).
Right click on that folder.
Choose the option to "send to"
Click on "Compressed zipped folder"
This will create a new folder in the same directory with the same name excepted compressed.
