You are DEFINITELY my new hero.  This worked perfectly and thank you so much for posting it.  I was able to wach the Blu-ray of "The Hobbit: The Desolation of Smaug" for the first time since buying the movie.  Unfortunately, I had already spent $80 on an external Blu-ray player for my computer since there didn't seem to be a fix for the drive in my computer.   However, I'll keep it as a backup because the same problem may occur in the future.  Thanks again. 
Hi there, I previously went to ask this question on CyberLink's support forums but they directed me here because apparently this is a Dell-customised piece of software... My problem is, I recently got a new Blu-ray. It was released only a few days ago - Glengarry Glen Ross. Every other Blu-ray I put in my Blu-ray drive plays just fine without any problem, but when I stick in Glengarry Glen Ross it always comes up with the following message: "AACS License Key Update: An important component of CyberLink PowerDVD requires periodic updates. New movies may not play back if the component is not updated now. Would you like to update now? (Error code = 0024)" and there is a yes and no button. Every time I hit "yes", it will try to download this update but it will immediately throw me back to the same message about 3 seconds later in a continuous loop. So basically it will not let me play this Blu-ray which is a real shame. Does anyone have any ideas on how to fix this? I'm using CyberLink PowerDVD version 9.6.1.3522 which came pre-installed with my Dell laptop. I've got a Dell XPS 15 (L502X), HL-DT-ST DVDRWBD CT30N Blu-ray drive apparently just using Microsoft's drivers, and I'm running Windows 7. Any more techie info just ask.
