I had this very same problem. I e-mailed Daz, including my order number, describing what had happened and detailing my system. Within a short while, I received an e-mail from DAZ giving me a password to a temporary site where I could download the items I had ordered. I'm sure they'll fix whatever's gone awry in short order, but in the meantime, just contact them. In my experience, Daz have never been less than fantastic.
