[Bug] "Test version" of rescue media although created from licensed program

I created a rescue media (CD) from within the installed (licensed) program. I booted with this CD and tried to clone a disk. After having set all cloning parameters the program told me that it can't execute the process because "this is a test version of true image" (translated from German).

As a "work-around" I downloaded the rescue media from my Acronis account, which then worked - however, I consider the above as a bug.
