Had to replace hard drive in Windows 10 pc. Afterward, (with clone of old drive); trouble registering CD Architect. Found a way for Magix to recognize my product, but it wouldn't accept "ComputerID" that was given to me before Magix acquisition, nor the one found in computer's settings. Attempting registration thru program asks for reinstall of program. It was downloaded several years ago. Scouring Magix site; CD Architect is nowhere to be found.
