I am setting up ZenCart (1.50) for first time to handle downloading MP3s. I have added the product. I have set up an Attribute for Download with a Value of MP3 and a radio button. I have uploaded the files and they show up with the green dot on the Attribute page. When I try going through checkout, they show up as downloadable purchases but then nothing happens. There is no link or email so that the customer can actually initiate the download.

Also, at one point in messing with the product specifications and the attributes, I turned on a little blue icon that said "Buy Now" instead of the quantity box, but I had no idea how I did that and subsequent work on the site made the blue icon disappear and I have not been able to find out how to turn it back on. I liked it.

Can anyone help me with either of the above two problems?
