When you purchase a PC Disk Clone X, you need to register the software. However, you might encounter an invalid license response even you have a valid license. After a while, the possible problem may be discovered.

When you enter the order id and email, please ensure there are no trailing spaces. Sometimes when cutting and pasting the order id and email, there is a blank space at the end or at the beginning. After order id and email are submitted, please be patient and wait for a couple of minutes when the license code is being verified.

Besides this problem, PC Disk Clone X really did a great job in Drive Cloning and Drive Imaging.
