ReachView to ReachView 3 app transfer

Hi,

I’m currently faced with a corrupt survey file which was downloaded from the original reachview app. I have transferred to the new ReachView 3 app and can’t access any of the original data which I had on the original app. I don’t have access to the original app any longer so can’t go back and redownload my survey from the RS2+ rover. Is there a way to access this survey from the new app or by plugging the rover into a computer?
