I've installed the application, but since I don't have a device to attach, it's impossible to select tracks. I've also tried to find certain sample data to load into the application and the results were the same.
There is a manual that you can access through the main menu of the software. Go to Help > Manual and wait for the PDF file to open. You can check the PDF file to see how to work with the software or what you have to do to work with multiple tracks.
