When in EN-Windows, try hitting the 'F11' key on your keyboard, or via clicking Menu >View >Note List, so that your 'Note List' is displayed. Also, and just as an aesthetic thing, so as to give you more screen space to view the note editor/note content...I would resize your 'Left Panel'... simply grab the right vertical edge of the panel with cursor and drag. You've already tried the File > Exit and restart option, so that's unlikely to help. Also, have you tried creating a new note 'CTRL+N' to see if you're actually able to do so? Finally, after you view your 'Note List' (F11)... also try F10 to toggle the 'Left Panel' on off (whilst Note List is still displayed)...quirky things can works sometimes
As for your secondary problem...I think this is due to you having a Basic/Free subscription, in which case I believe EN does not provide basic users support.
Try going to 'Task Manager' and closing/exiting out of all Evernote Processes, then restart the app...might work. Also what did you use to pixelate your image? cheers
