Loss of DAW control

Lost daw control with my Nektar Panorama T6. Worked fine in Windows 7. I invested in a new desktop pc and upgraded to Windows 10, re-installed Cubase Artist 10.06 and then the Panorama T6. The T6 appears in the midi manager. I can play notes, modulation and pitchbend but the record, play rewind etc., don’t do anything. Nektar have told me to re-instal Cubase - is that really necessary? Where should the T6 dll file be located?
Any help very much appreciated

This extensions are installed with cubase. (at least on OSX, and it used to be so in MSWindows too). So very close to the cubase.exe.
