PS1: No, It was 100% SUMake 2017, working OK about 2 months. (I use SU from ver 7, and I kbow differences between Make and pro-demo) - but it was 1st what i chcecked

PS2
I tried web-based "Free". It's a kind of nightmare.
BTW - I have plugins I've paid for. Something is not fair... Not good way...

OK.
But my sketchup make 2017 just STOPPED WORKING.

Licence text means: "user, Sketchup Make 2017, Trial version Pro, expired"
And I can choose between free (web based) or trial pro.
J want my MAKE2017 back.
I tried to reinstall, but with no resylts.
Any ideas? Any help?
