HELP PLEASE

I purchased Cross DJ on Saturday, and despite getting in touch with customer services I still do not have a working copy.
I am able to download the Zip file from the link sent to me, but when I try to unzip it I get a message saying “Cannot open file, it does not appear to be a valid archive”.
I am using windows 7, and have tried downloading with my firewall and all security switched off and still get the same message, my winzip is fully up to date too.
Please help bring this saga to an end.
