I dont know what else to say. Just vanished, they were here and now they are not. I tried to reinstall the plugins to have presets back but i get error. But this only happened to FX plugins (including guitar rig). At first it was also on Reaktor 6, when i tried to load my custom reaktor ensamble patches, i was told im using player version and every ensamble from K11U was gone, but after 30 seconds or so everything went back to normal in front of my eyes. But FX plugins presets just vanished and do not appear.
