Sketchup licenced expired after 24 hours

my employer just bought me a new PC and I wanted to test sketchup on it with the trial 30 days version.

I’ve installed Sketchup Pro 2017 and everything went fine.
Then I realized that the plugin I need does not yet support version 2017. I reinstalled the 2016 version and installed the plugin (Octane Render) ok, and everything was worjking yesterday…

This morning when I launched Sketchup… it displays a msg “Licensed expired”… which I don’t understand since I installed it only last night.

Could you please help as I’d really want to test Sketchup 2016 with Octane Render for my new job.

Thanks in advance
