I'm playing the CMBB for Vista version. I've just completed a PBEM battle with a friend. No problems.
Now, he sends me a new battle and when attempting to load it I get "File is meant for a different edition of Combat Mission".
I recall this occurring when we tried to play a CMAK battle that he sent. It seems fine when I send battles generated on my computer.
Any idea what the problem is, or how to fix it?
