It might not work if you are using a CD-only OOB - Georgia say, that the free demo users dont have access to. If you are getting OOB errors - ensure that you have exactly the same OOBS (have the same version of the game properly patched up, and no-one has done edits).

But otherwise as Don says provided you the CD owner have used one of the first 5 PBEM slots that the free DL user is restricted to then all should work OK. Also provided that that no user is trying to "share" a slot i.e. trying to run several games in say slot 3, as that will screw up the PBEM system. One game, played in the one slot, till completion.
