I also was surprised to find the Evernote Helper missing in an upgrade as I use it every day. I saw all the warnings about not updating to the new version and accidentally did an update not thinking about it and now I am also in a world of pain and need to revert back to the previous version.
I also lost a few days of notes in my Evernote Helper that wasn't saved. Is there anyway of getting this note back which I was working on in Evernote Helper?
Also, how do I downgrade to the legacy version?
Thanks
