This has made me reluctant to upgrade to PD18 as I don't want to lose the rest of the NewBlue video essential packs and also the BorisFX packs.
I'm not sure where this came from originally but I believe they were packed in with the original installer.
So, does anyone know what I'm likely to lose by ugrading? I'd try it myself but I don't think there's an easy way to roll back once you've upgraded.
