by we are3 using the same computers - you mean you share a PC? - PBEM won't work on the same box!

CD and DL games should be able to PBEM. So something else is likely up - e.g. different versions of V13?.

If your opponent is using the same slot for multiple ongoing games then any PBEM is toast since the registry slot for both games will be getting out of whack. The slot used for a game must be the same througout the game - no loading other PBEM games into the same slot.

Secure PBEM is really for competitions etc., basic mode should suffice for friendly games.
