With Sony MSP12 I also had a number of NewBlue Videofx ... these were fre addons ........... do you know where we now obtain these (had to do an MSP re-install)
Sargan, see if newbluesonyvegasmspps12setup14.exe on
http://download.sonymediasoftware.com/current/extras/
is the one you want.
You may also be able to download them if you visit https://www.sonycreativesoftware.com/myaccount/myorders and click on your MSP12 order. I see add-ons to download including New Blue Video Essentials VI when I click on my Sony Vegas Pro 13.0 order.
I had initially gone there and had an auto-redirect to Magix ..... though you are correct I did find them in myorders
