Can't see norton utilities

i purchased NU 14.0 as an add-on with my NIS 09 renewal.  when the computer boots or when NU icon is clicked norton utilites shows up in the task bar but no window shows up on screen.  Support had me use removal tool and re-install to no avail.  i have to control, alt, delete to get the NU out of the task bar.  I am using a microsoft keyboard with a flip 3D button that can show all open windows.  when i do this i can see the activate NU window but i can’t get the window to show up in-screen when i return to single view.  any thoughts/help would be appreciated.
