After several crashes of cinema, I come over here and lo: the problem has already been mentioned. So: same problem here. Luckily the manager works. perhaps simply remove that screenclutter alltogether in an update?

this said: your pdf gives a detailed overview of what it all does, but nothing on how to do it or how to use it.

I load a cube, make it editable, add an uvw object, get  a new tag with lots of options, can movescale and rotate that lila line cube with interactive.
But no way I get that cross (four squares in a row, and on second or third one on top and one below). I cannot select on that uvw object, cannot set it to point, edges, polys. So why is it for?

Please create some simple tut or a movie or so in which you show how to use your plugin. I told Erik to buy it for me, which he did, but now I'm stuck.
