Licence agreement - problem

Hi guys,

I need the help please. I bought Pocketbook PB611 e-reader few weeks ago and after uploading few books, my Pocketbook just reseted itself. After that I had to choose language and confirm Licence Agreement but I clicked on the disagree button by mistake :-(. From that moment I cant get to the next screen. When I turn on my Pocketbook, it always wants to choose language and once I click on "Agree" button in the Licence Agreement page, it always returns me to the previous language page. What should I do?

Thanks for help!
