Can't create a lingq "error"

Hello, I have imported a lesson “Sur les toits de Paris”. Then an error-sign appeared: “There was an error opening this lesson, you will be leaded to the home-page”. It was not possible to create a lingq. What can I do? Can you fix this?

Hi Simona,
Can you please contact us on support(at) and send us link to that lesson so that we can check it? Thanks!
