Suddenly I am unable to drag PDFs into EN. I get the error message: "The file xxxx could not be imported" "It may be damaged or use a file format Evernote doesn't recognize". I have tried to drag PDFs that I have previously successfully dragged into EN and get the same message. I also did a reinstall of the latest version and same problem. I am a Premium member and I was away for a couple of weeks so maybe there was a major update? I also notice my Notebooks are different color.
