Problem with saved files
Hi, I just downloaded Geogebra classic from Windows Store. I had Geogebra 4 on my last laptop. I opened a file that I had saved into my drive. It works, I modify it save on my desktop and when I open it back I see a brand new Geogebra file with nothing on it... So I go back to my drive, download it again modify it again, save it... same, nothing left on the file after I closed it... What's wrong?
