Have you reported these problems to technical support? I haven't ever experienced a failed download with the 810, even when I was using the beta software. And although I've set up several complex home theaters with ProWizard, I haven't ever had a configuration take longer that about half an hour.
But that doesn't mean you're doing something wrong—we'd love to get your feedback through "official" channels to help us understand where we hit the mark correctly and where the flow of ProWizard needs improvement. This is our first wizard-based remote, so your feedback helps us to refine the remote, the wizard, and future products that use parts or all of the wizard logic flow.
Best regards, Dale
