I logged on to SketchUp Free just now, and suddenly all my projects, that I have spent maybe 30-50 hours working on, are gone. I have checked that the account is the right one (using gmail).
Also it seems that it does recognize my three projects initially since it shows a glimpse of three images when I log on, as if it has detected something, but then in a millisecond it removes the project-“gallery” and treats me as if I’m new and have no current projects with the sign: Welcome to SketchUp! start modelling
What to do?
