Problems with Remote Front Panel

Hi, I've seen "How to create a LabVIEW Remote Front Panel" video of Grant H.

I've followed the steps to create a remote front panel but doesn't work. When I open the URL in Explorer, show the title, header and footer but don't show the front panel, only a image that say: "Downloading front panel 0.00% of 0 Bytes" and don't work.

My Remote Front Server in turned on and I'm using LabVIEW 2010 in Windows 7.
