I don't know why I tried to activate this plugin yesterday, as I already have the stand-alone version of SNGWiz. But everything seemed fine yesterday, today though, when I run HEM (version 1.11.06g), I see a little portion of a Wiz window in the top-centre of the HEM window (this looks like some sort of graphical bug), and when I try to navigate the Sidebar, I get an exception error no matter where I click.
How do I undo the Wiz thing and get HEM to work again?
