I have used Creator for years. First was Creator 6 or 7 I think.
Anyways... I have Creator 10 on multiple machines, including 2 brand new ones I just built. They are identical to each other as I bought 2 of each when I purchased components.
I cannot burn "Create Music Disc Projects" on one of the machines. It will burn data discs, but not multiple disc projects, saying "Insert a Blank Disc".
I have installed, uninstalled, reinstalled multiple times. I even tried a copy of Creator 12, same results.
