I have a demo version of NERO 5.5.2.4. It is suppose to expire on 7/31/01. I am trying to burn a mixed-mode CD. When I open the .nrm file, it tells me the demo has expired (even though it is not 7/31 yet). But it still opens the session. When I open the Write-CD-Dialog then click "Write", it starts, but then I get a "power calibration error". In the help, I could not tell what this means. Does anyone have any idea?
