Multiplayer reloading game problem?

[Third-child]

Ok 3 of us were in a game, and one crashed. Once we restarted and tried to load up again, 2 of us (not the host) got this message?

"The save file you have selected is protected to ensure that the assets in your mod folder have not been changed"

Then if boots off the game and returns to the desktop?

Anyone know why? Or how to get around this?

I got the same problem!

I play together with 3 friends. When we try to connect to the host, we all get an error message, something about different versions?(we all got the same versions!)
From here on the games works perfectly, but when we try to load the game, we all get the same message:

"the save file you have selected is protected to ensure that the assets in your mod folder have not been changed"

then CIV4 crashes....

What can be done, please help

Have you turned "no cheating" on? I've heard this can cause this problem.
