By failed file, I mean a file that wont load. I believe files are incomplete, truncated.
I start game, click "Join Multiplayer", click "Load Email" button, select specific file, screen flickers & nothing happens.Keep in mind this has happen to about 20 of 100 files, a minority.
What all failed files have in common: The last line of files received are missing the statement "End of PBEM file" [not exact quote, but close].
I also saved a failed file to compare to a successful file & counted several lines of text missing at the bottom [along with closing message I mentioned].
Im not sure what CM versions my opponents are using.I'll check into that. I will say that majority of contacts have enjoyed 15-20 file exchanges before problem occurs.
I suspect mail service.
