I just switched from mac to a windows pc. I installed SketchUP pro 2015 on the new computer and it worked fine. I just upgraded to windows 10 and SketchUp Pro 2015 worked for one day, then it started freezing right after start up and shows as not responding. I uninstalled and downloaded and installed trial version of SketchUp pro 2016. It worked just fine for one day, and now I have the same problem. I checked for compatibility and its says there is a problem. Has anyone else had an issue like this? I need to get back to work!
