PLEG device hangs when I try to view/modify settings

I am in the trial phase and so far really like the plugin. But after 3 weeks, before the 90 trial, it seems to have stopped working in UI and just hangs. The ICON has be replaced with default ICON and when I click any tab, it just clocks. Opening … but never comes back. Looking at the logs does not show much. Has anyone had this issue? Any clue what I did wrong to breat this?
