I have been unable to get Nitro PDF Pro's window to open from the taskbar despite it showing that the program is running. The program just went into this state suddenly.
It shows open on the taskbar and reads as "Nitro Pro (Expired Trial)". I have a license.
As mentioned in title I have tried to fix the problem by restarting computer (several times), re-installing nitro pro (several times), and clearing .\Nitro in %appdata%. These have not fixed the problem.
