HELP with Downloads!

I am doing a new load of my shoping cart and I upgraded to the newest version of Zencart. I cannot get my downloadable files to show a green dot.

My shop is at http://www.krwknitwear.com/shop

The files are in the shop/download folder

I have all the settings right as far as the faqs and the Forum are telling me. I dont know what I am missing.

I have one free pattern in the cart right now. It is downloadable only.

I am using Download by Streaming in the Atributes settings. I have no idea what is going on. On the old version I had no issues. My cart is on a windows server

Any help is greatly appreciated!

You've configured your attributes oddly.
When trying to add-to-cart, the following error appears:> Please correct the following:

On the Option for: Download You picked an Invalid Selection: PDF VersionHave mistakenly configured the "PDF Version" choice as read-only?

That is it! THANK YOU! I am not sure How I did it.. but I went back and deleted the Atributes and re-did them... now it works great! :)
