Fix DiRT 3 PC "save failed" error - no patches, downloads
Thumbs up so I know this worked for you! This solution only works on the Dirt3 GFWL / Steam version! Does not work on the Complete Edition, nor pirated versions.
When DiRT 3 refuses to save, it's usually a problem with a corrupted profile folder. By renaming the backup folder to the regular save folder, DIRT3 can overwrite that folder with the new progress.
I am NOT showing how to recover old profiles, I am OVERWRITING it with the current progress immediately when the error occurs. If you don't save while the game is running, once you exit the game, the new progress is lost.
This works for both Online & Singleplayer modes.
