I edited a note with important informations and it's all gone, I have lost the whole content. How can I recover the edited content of this note ?

Hi.  It's good practice - particularly with important information - to keep one or more backup copies in different places in case of situations like this.  Unless you can find the note in the Trash notebook,  or have a system backup that might have included a copy of your Evernote database,  it's unlikely that it will be possible to re-create it.  Have you checked the server copy of your database for this note by signing in to Evernote.com?
