Help to repair the save (license>pirates) (Assassin's Creed: Odyssey)

Took the game on a trial license (Uplay+)
After the subscription ran out I wanted to continue to play and I downloaded the pirates (Other s) and using the Converter of savegames suffered saves with a license for the pirates, in the game they appear. but trying to load the game gives the inscription Your saved game needs to be updated. You will not be able to continue without updating. On the Internet about it so nothing was found, and progress do not want to lose..
