Hmm I'm wondering why the files aren't showing up then. When I hit the button here saying add attachment, look for the file in the folder I know it to be... it is empty. But If I look at the folder on my computer all is good. It just isn't showing up when I try to add the attachment. It just says "No items match your search". But, I know that I have PDF, Mobi and ePub files in there. I checked before I came here to upload it.
