It's says that if the price is set to zero it will display a download button but instead it just uses a hyperlink. I could not find a free download button image in the package so I'm guessing this is a mistake?
I have made my own free download button in the same style. I have tried looking at the code in order to fix this issue but I can't work it out. Any help would be much appreciated.
Other than that this plugin is awesome!
