It should start like this I believe.
The first turn you would setup the parameters, choose your password, click OK to save the 001 file and send it to me.
I open the file, choose a password, choose my troops, click OK and send you 002.
You open it and choose your troops, do your setup and first movement orders, Click Go (the red button) and send me file 003
I open 003 do my setup and move, click Go. save and send 004
You open 004 watch the movie, make your move send me 005....and so on.
