OK, just tried latest Silver5 version
1. I followed your suggestion of:- you could also try to click on Settings/Activation & then click on "Enable" and "Maps and
speedcams" then on Save. When you will start the tool again it should activate all maps in your TomTom.

Correct BUT although it activated the UK map/speedcams & my voices it hasn't done the Truck v901 map or speedcams in there and it's now frozen where it's listing MAPS FOUND etc

I really think that before you release a further update it should be thoroughly tested by your developers who have a couple of different maps/speedcams/premium voices etc and, ideally, with a couple of different navcores too??
I'm happy to test it BUT I don't want to be the one who keeps finding major problems with it.
Once YOU guys think they've got it right then by all means re-release it & we can check/test it THEN
