No file paths defined

Post a screen shot of the downloadable files panel – this error usually means this section is empty: https://dl.dropboxusercontent.com/s/yui8vfi6dk5ad1n/2014-06-24%20at%2017.48%202x.png

hey,
I have the same problem, and the section you mention really is emply to I added a file using ADD FILE button, but now error changes from “no file paths defined” to “file not found”
