One workaround to this problem, which is infuriating, is to replay from the turn prior to the error. So long as your email saves outgoing mail, your opponent will have a copy of it to resend and you can try to replay it from there.
Not sure if that will eventually result in problems, but its an option ...
Actually -- if Andy or Don knows whether that approach will eventually fail I'd like to know now to scrap 2 games I have in progress, one where I accidentally tried to open game on wrong install and one where my opponent (I won't mention who embis, so as to preserve your privacy! =) did.

Here is the work-around I've used: Just take the last "good" save that you accidentally tried to play out of wrong installation, and reinstall that same file in the correct slot and go from there. I figure the correct install doesn't know what happened on the incorrect install, and unless the security system uses some kind of quantum-physics-esque "i know whats going on over there" string-theory type of knowledge, the game should be none the wiser.
