Corrupt Save Data Detected (Guitar Hero Live)

Guys, can someone faced with such problem:
I went today to Guitar Hero Live and the game gave this message : Corrupt Save Data Detected something like that. The choice was to delete save data or not to delete. Choose NOT to delete the game then this message is not eventually chose the 1st option and the game started from the beginning. Flew all points with songs from a career, but survived(thank God) status in GH TV. strangely 5 minutes later went to Quickplay the songs have points began, but closed songs never opened(like the need to re-play the gigs). I don Nitsche not know why and why it happened, who knows how to take it all back ?
