@pierreconti We ran into this problem months ago and haven't fixed it. Could you please look into https://app.workbenchdata.com/workflows/18232/? The files are all gone because file upload was broken when the workflow was created.

I think you'll need to duplicate the workflow and re-upload the files. Then, please change Lesson VIII (in both English and Greek) to point to the new CSV.
