I've been with Independence since they were Yellow Tools, and I just completed a new build, and ran into the same exact problem. When Magix acquired Yellow Tools, I accepted the upgrade and maxed out with the then promotion, and at that time it was just "Independence Basic and Independence Pro Plus Library "70 Gigs". Now they have a total of 3.
1. Basic 2. Pro Plus. 3. Pro Plus Premium
The 'NOW" Pro Plus Premium 70 Gigs was the Equivalent to the Pro Plus "BACK THEN"
I still have my P2 serial number for my stand alone (70 Gigs) but it doesn't work !!!!!
