After having studied German here for a couple of days I lost all my lessons, links, words, etc. I have to start over. How can I get my lessons back?
problem solved, thank you for attention 
Hi Olga,
We’re not sure what went wrong there, but it’s good to hear it’s working as it should now. Don’t hesitate to let us know if you experience any other problems!
thank you Alex, it was my mistake as a newbie here
