I have a genuine CD with Paragon Hard Disk Manager 15 on it. I often boot directly from the CD without any problems. However, today I went to backup my desktop computer and when I attempted to boot from the CD it puts up a big blue screen with the Hard Disk Manager 15 logo at the top and then a box appears in the centre of the screen asking me to enter a password. This has never happened before. Why is it doing it now, and what is the password? I don't remember ever having set one up.

Any help appreciated.
