New saves are ok? The game has changed the way it saves games over time. I can only guess that old saves may not conform to the current way games are saved. Maybe a 'save as' may correct the problem. Save backup will be created the second time the save is used. When you create a game and save the save folder should be created w/o a backup image. The next time you re save that game the old folder is renamed with a .backup and a new folder is created when you save. If the game is not saving properly free space on the hard drive may be an issue or a user rights issue or maybe the antivirus may be interferring. A guess as the game is patched the game may not recognize old save formats.

Sorry, should have covered the AV and space issues in my first reply. I've got 20Gigs free on both my HDDs and I've tried entirely disabling AV and the problem is persistent. Of course that does leave the possibility of a rights issue, but I'd rather not entertain the thought that I'll have to disable all the irritating, but effective security built into this annoying OS every time I want to play S3. That and disconnect from the internet. Besides anything else that would require a restart before then after playing and the game launch is slow enough as it is.
How many save games do you have in your saves folder ? There's only so many you can have.
Did you try moving a few old ones o a different (backup) place and see if the new ones then show up ?
