I had have the same problem and I lost two hours of work; this happens if, for example, enter into other applications still leave open the program and when you come back you forget that you had already opened.
I know that it's possible to manage it manually but a "Warning" as MUR suggested should made more "user friendly" the programm.
Several copies of a project, open at the same time.
