I tried looking online and can’t find a phone number for sketchup, does anyone have it?? I want the the SU 2017 version back but it will not allow me to reinstate my license. I did a full clean sweep of the computer thinking I had other issues when it was clearly the 2018 version that is the problem. Now I did NOT remove the license when I uninstalled it, did I screw myself by not removing and uninstalling other 2017 and 2018 versions by loosing a seat??
