Corrupt save files??

I have downloaded the game after few months of break and now when i launch the game it says "

nfs unbound your save file is corrupt and could not be read by the game" 

It gives me an option to overwrite which is just starting the game from scratch.. Whats the point of grinding this game or rather even playing it if we anyhow are gonna loose the progress. Really disappointing. I liked this game a lot but my opinion is changing now
