I'm desperate. Yesterday I downloaded the new software update for Tracktor Pro 3. I no longer have my 10,000 songs in folders that over the years have been in the best format for me to perform live. I perform several times at the United Nations, Weddings, sweet 16, old school events. Therefore my folders / playlist are about 15-20 for the various music I play . Not just a few genre. I keep all my music on an external hard drive. When I purchased the S4 a few months ago I also got a new laptop. Following all the instruction to transfer the music, stripes, and folders was so smooth. At that point I was just getting use to the new hardware and performed at 5 events with no issues (it was fun). I believe that every time you close the software it creates a history of how your folders may have changed along with all your hardware settings. Can I use an old saved settings in "COVERT", "BACKUP" "HISTORY" to add those playlist back into the new software? If so how can I do that? I hope I'm clear with my explanation
