since smartPad was working before and you did not update it, normally there is nothing to fix on smartPad...
you changed image on hdd and that is where i would look for trouble.
are you sure that image is ok? are you sure that image is complete and not just windows?
if it is only Windows then Sunrise still need to be installed.
Thank you for your reply.
I had to install the SuriseOS from SunriseWorkbench under StationSetup - Install - InstallOS. Then the KRC restarted, the smartPad was re-configured and updated end everything works as expected.
