Wigam can't load my turn, any ideas?

minimum security, but I think that just turns off the load/save/crash counter. Have you switched machines? I don't think that will cause a problem with low security set, but I really don't know. Re-zip and resend is all I can think of. Make sure you are zipping from the correct directory. At least you can't be that far along yet, so if you have to restart, you won't lose much. That error message is what you get when you try to load an MBT file in a WW2 game and vice versa. So check you path statement when you are zipping the files.
If Wigam was extracting to the wrong directory, I think the error message would be something about path to game has changed.
