I just encountered this issue for the first time these past couple of days :( I'll save the file, but it reverts to the older version when I open it up. It's weird because the THUMBNAIL is right when I go to open the file, but then when the document ACTUALLY opens, it has reverted to an older version. This has happened to me two days in a row now and I HAVE the most up to date version of Illustrator. I'm uninstalling and reinstalling as suggested here, but I've now lost a whole day of work on something that has an impending deadline and I'm not happy about it.
