I can no longer successfully launch the tpPLC utility to display my connected PowerLine devices. It's the latest version from 2018-08-16.
I'm running Windows 10 build 1809. Previously, the utility launched fine. Now, it launches, asks for admin permission, then shows the blue window, but only a spinning icon in the middle. No adapters are shown as before. The app is unresponsive to pressing the icons on the left column.
I've tried uninstalling and reinstalling this utility several times without success. It does launch on a different PC and Mac, just not this one.
I called tech support, and they promised to ask the developer, but they never got back to me. Any suggestions?
