I don't know why the files are displayed like that and why you have three or more "BecomeARockStar-0.45-pc" folders, one inside the other.
The first three objects are not supposed to be folders, but files. You usually launch the game by (double-)clicking BecomeARockStar.exe.
If it doesn't work, rename those three files (or move them somewhere) and use the ones you already have from the previous version.
