The same here, Bob. I think, the zero "Download (0 of 10)" is the same as a I see at DAZ 3D: You're able to download this file up to 10 times (for example, if your download crashes).

I've got the following message from contentparadise.com:

Due the the high demand for the Poser 5 free download your download has been delayed temporarily. Please wait several hours before attempting to download again.

We apologize for the inconvenience however your Poser 5 free download will remain available to you through the MyStuff tab indefinitely.
