The license that was loaded in one of our AX 2012 databases expired, and, after it expired, the navigation pane is completely gone and no companies show up in the address bar (although the company code is in the right corner).
I used the AOT to launch the license form so that we could load an updated license (which worked); however, the navigation pane is still gone and no companies show up in the address bar.
I have recompiled all of the objects and synchronized the database, but no luck. Has anyone run into this before?
