corrupt save games

does anyone else keep getting corrupt saved games.

i save my game everything looks good i come back and try to reload and get "Unable to load game c:\.........."

If any of the SEV gods and uncorrupt a game i would be grateful this was the longest i have been able to play in the game 7.1 years

The last think i did was controled the computer players and got out of failed alliance that i did not need to be in (i know its "cheating") but that has worked with out error before so i do not think that is the problem i realy dont want to goback to the only working autosave casue it was so longago
