Upgrade from v2015 Premium to v2017.2 Premium. All the BI Explorer Views & all company codes (checked so far) are all totally blank with no data, no Settings (not even STANDARD) are present. The Navigation Pane > Preview Pane + Explore + Tasks are all missing as if just an empty BIE shell is there. I suspect this is some Premium trickery, has anyone encountered this or have any idea what may be causing it, never seen this before or what to do.
