NI Komplete Kontrol S 49 Mk.2 setup help!

[Slotunes]

Just received a KK S49 Mk 2. Setup stand alone mode, download sounds and playing all went smoothly.Also loaded vst64 folder in Reaper.I even put a track in reaper and can get Organ sounds via the Reaper midi keyboard only, not the S49, so my Midi settings are wrong somewhere. When I went to Midi devices in Reaper, The KK Daw/Ext and KK-1 choices come up and I get control panel error comes up. Any help much appreciated!
