@shortline, the screen shot you showed is the result of a Spotlight search, not a directory or contents of a folder. It is showing you a bunch of backups previously stored on your Mac.

You need to be sure you downloaded the latest program version here. Open the disk image and drag the program to your Applications folder.
I believe the reason you cannot find your old files is related to a change in the default location of your application data folder. Either modify the location to the old location or import the businesses from that location into the program, which will store them in the new location. This was discussed here:
Read the entire threads, because the change originally looked like a bug. Solutions are described.
