Sorry you're stuck but there's almost always a pretty easy fix! Do NOT try to start all over again, uninstall Max's Pitch Package, etc. That can make it worse. There's a 95% chance the same snag/fix is listed & answered in the Help FAQ. But if you can't find it there, post your problem here.
Make sure you post in the right category below & be sure to include a screencap showing the issue!
Looks like you maybe selected a shortcut to the file, rather than the file itself. It's saying it can find any data in the file. (It doesn't follow shortcuts to the file itself.) Try finding the file itself (not the shortcut) and dragging it over and dropping on there. If that still gives the same problem, then the file is empty or something due to download issues. Try downloading again and then try importing again.
