None that I can remember. This computer is in my recording studio so I don't really run much variety of software on it. I might have upgraded the video card a while back but don't know if that was before or after installing PD11. The GPU is a CUDA-capable nVidia 9600GT. But because I'm running XP, I have to use CL graphic acceleration as opposed to hardware acceleration. But this computer always ran XP so that part hasn't changed.
The error messages I get complain about my mpeg & h.264 codecs needing activation. Everything else seems to work just fine. The only other thing that changed was that I haven't used the software for a few months. Plus I changed my registration email. If CyberLink has been sending me emails, they would have bounced. But I don't see why that should cause any problems.
So I spent a whole day trying to get PD11 to work. I uninstalled the entire package, Ultra, Essentials, Premium & WaveEditor. I even unistalled QuickTime because that probably got updated after the PD11 install. Then I reinstalled the whole thing, activated it with my key and registered it with my new email address. The software was activated but the two codecs that stopped working still don't work.
Do you have any ideas?
