Just purchased a copy of DVD Architect Studio 5.0 from Amazon.com. I previously had a 30-day free trial version which I removed via uninstall from my computer. After downloading the purchased version, every time I try to activate the software with the supplied key, the software cycles thru the same GUI stating that my old 30-day free version had expired and I need to purchase it (which I had already done). Apparently there is a piece of the original code resident on my computer that didn't get deleted when I went thru the uninstall process. Is there a skeleton key you can provide to override this problem to activate this software?
