Hi, I'm very worried. I installed Course press pro a year ago and I put all the material for 2 online courses. I never had a problem during this year some days ago (I don't konw exactly when) all the material dissapear (content, videos, pdf, everything! for the 2 courses), I don't understand what happened. Then I thought I had install the new version for the courpress plug in, i did it and all my website dissapear. I have tried twice. I have to restore a back up copy of my website. But the units are not there.
