Hi Barry -

That's weird! I wouldn't have thought a system update would interfere in that way.

On the NewBlue FX names, have you checked the .xml files at C:\Program Files\CyberLink\Shared files\Plugin\NewBlue to see that they're in order? (not that you should have to)

I don't actually have the Motion & Paint effects installed any more, so I can't check the appropriate strings in the .xml filesm but say for Art Effects there's an .xml file called NewBlue_PlugIn_ArtEffectsBundleForPDR_ENU

If you open that document, look under String Table. The first entry under String Group should say:
stringID: IDS_DSP_V1_NEWBLUE_PASTEL_SKETCH
stringCaption: NewBlue_Pastel Sketch - that's the name that's applied in the PD interface

If you don't want to bother with that, maybe re-installing on top of the Windows 8.1 update might resolve it.

Cheers - Tony

I'm doing the re-install as I type, Tony. Of course I had to hunt for the CLcleaner tool, I'm gonna add THAT link to my site if I ever get any time. Oy.
It's just another flavor of fun in the layer-cake of issues involved with the oh-so-time-consuming hobby/business of video.
I'll keep you all updated, as well as New Blue, who got back to me in a few hours on a SUNDAY. Their download was no different, but they did respond. HP Envy Phoenix/4thGen i7-4770(4@3.4GHz~turbo>3.9)

OK, so...
a re-install of PD11 fixed the naming issues, and also allowed me to then remove it (PD11) successfully.
I would also like to add it completely removed the 2 New Blue bundles that came with it (the ill-named ones).
That fact is just about the stupidest bit of programming I can think of (other than the Obama-care website).
So, I guess I'll re-install PD11, then try and find the relevant New Blue folders to save.
Sometimes I wonder if it's all worth the hassle...

The CL Cleaner tool is no longer recommended by CyberLink support, unnecessary for PDR13. I wouldn't choose to use as it* (the little program) just "fools" the control panel and little else.
*CL Cleaner for any of the earlier PDR12/11/10 builds.
After CLCleaner was activated etc, PDR could still be used to edit with etc but not uninstalled via the Control Panel.
