[Plugin: Easy Digital Downloads] File limit per download?

Does it do that on all Downloads, or only that particular product?

This is the only one I had tried to add this many files to. I just created a test download and added 9 files to it with no problem. So, apparently it’s just this particular product. It has 8 mp3 files, and I’m trying to add a zip file to it as well.

Could it be hitting a total file size limit?

On another download you are able to add more than 9?
