Sorry you're stuck but there's almost always a pretty easy fix! Don't try to start all over again–not necessary! Don't start undoing stuff and don't uninstall Max's Pitch Package, etc.
There's a 95% chance the same snag/fix is listed & answered in the Help FAQ. Check that first but if you can't find it there, post your problem + a screencap in the proper category below & we'll post a solution back ASAP!

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.
