My problem is that I can see the expansion pack inside FL studio when nexus is opened. But I cant load the sounds/presets in new expansions pack. It says "The expansion product is unknown. Please contract refx support. Output has been muted". Other sounds is working fine.

does anyone own the nexus 4, and expansion packs, just done a reinstall of my os, downloaded from refx portal, would not show in factory directory, looked in nexus nks folder, no nksf preset files, messaged refx about it, they have just told me they have dropped support for nks, bummer, so i really need the nksf files to get nexus back up and running in my s series mk2, browser wise, would be a great help
