Is it a brand new blu ray disk? Like a movie that has been released in the last couple of weeks? It may be an issue with you not having the latest AACS keys (the drm copy protection). I was getting this error with my version of PowerDVD 9 when I tried to play a brand new blu ray. Version 9 is no longer getting the proper updates for AACS keys but PowereDVD 12 is suppose to be still supported.
Try updating to the latest PowerDVD12 release (if you aren't already using the latest version), if that doesnt work I would suggest trying to use a blu ray movie that is older, if you have one. Like a blu ray disc that you bought back in 2011 if its available. If that works its almost certainly the problem with DRM
