New "assertion failed" error

[DaveConn]

This error has cropped up again in our long-running PBEM game. This time, when I try to combine the turns (I am the Spanish player), I get the error below. Any help/thoughts appreciated. Thanks!

Here are the zipped .rep and .sve file for ALL, in case that helps. (added .txt file extension to get them to upload, but they are zipped).

Would you mind e-mailing me the zip file at ericbabe@west-civ.com?  I can't seem to get it to download and extract properly.  I'm getting a 78k zip file that is an "invalid archive."

Thanks, Eric, I will send right now. Because the error happens when I try to combine turns, I will send the player turns that I am combining as well; I suspect you will need them.

On behalf of all the players in our game, thanks for anything you can do!
