Hi there,

This means the program cannot successfully verify the copy-protection on the disc after the installation. This might happen sometimes, even if the original disc is in the drive. As any hardware copy-protection, this is susceptible to additional problems, and some drives just cannot read it properly. Magix tech support can help you with this. Go to the support website and get the "Unlockmaster" download from the tools section. Run the application and request an unlock code for the Magix program you're having these problems with. This will generate a request in Magix' system and they will get back to you with the code.

I hope this helps.
