I managed to start downloading one of the files once today - but the server collapsed after 47Mb of download !!
I have the downloads in the "My Stuff area" so I think I may just give it a week or two before going for the download.
Biggest prob is that they are huge downloads and their server does not support resuming !!
By the way if you are tempted by the upgrade to version 6 check out the Poser developer website http://www.e-frontier.com/
because their upgrade price is lower (even with the 10% discount Content Paradise are offering) plus they will ship you a set of CDs.
