My opponent and I almost never use the resume feature and Im sure it was not used in this game as it was only turn 1.
We use the PBEM Helper to take care of save locations and unzipping files to the correct folders and I'm pretty sure it works like it should, i.e. unzips the savefiles to the 'PBEM Games' folder. Anyhow, if the game tried to load the last finished turn would it not just ask for the next players password instead of refusing to load at all?
I've also noticed when pressing '1' that the number of saves/fails for player 2 is *way* off, I can't remember the exact numbers but something like 300 loads, fails and exits

... could this be related?
