Please note this is urgent.
I had my liftetime's worth of notes in my notebook, and one of those notes was open in Chrome web browser. There was a network failure, and after it resumed, Evenote asked for my login informaton again. While I pressed the login button, ALL the notes in my notebook disappeared one by one. I refreshed, re-loggedin, etc. but the notes in that particular notebook are not appearing. (All other notebooks are fine). They are not present in Trash.
Please help as this might ruin my life's work.
