If you have any forms open with their model setting to yes, then the nav
pane gets minimized, and you can't max it.

So, perhaps you ensure no forms are open or run at startup and then try
again.

You also just create a blank database and import everything and you be back
up and running.

I would give the above issue a try, and simply ensure no form is open that
would "force" the nav pane to be minimized.
