When you order for download from Zygote, they send an e-mail with a download link and instructions. The link is good for two days (last time I ordered). I have heard that they keep good records, and if you lose something or have problems downloading, they will take care of it. They are good on the phone, too. I called and ordered all the new release animals when the store was down. I had them burn the order onto a CD. That was an extra twelve bucks. I placed the order on a Friday, and had it in my hot little hands on Monday.
