Something is fouled up.  It seems DXK thinks it is running, but is not.

I display TASK MANAGER I see Commander.  Then I see DX Launcher TWICE.

DX Keeper is not shown at all.

 

When I display Device Manager Ports,  I see communications port 1, port 3 and port 5.

 

When I look at the DXLAB Launcher display, it shows commander and Keeper as green, but the DXKeeper never opens.
