I did my due diligence in searching for an answer for this, but had no success.
I chose a scenario, picked E-Mail 2 Player, and typed in a password. After entering the password, the screen reverts back to home without any game play.
I sent the PBEM file to my friend and he had the same experience. He sent me his turn 02 PBEM and I still can't begin playing the game. We are just naming and swapping files without seeing any game play. We both have upgraded to 1.04
Thanks for your help!
