^^Just checked it out. The page loads up for me. I'd also suggest checking out your internet connection settings if upgrading still doesnt work. Depending on certain settings you may be unintentionally have your PC cutting off access to that website, which in turn would cause the same problem for your Wii browser as I'm assuming you're routing the Wiis connection through your PCs connection. Anyway it would normally have to do with the security settings if that is indeed the case, in which all you should need to do is lower the setting until your Wii shows a connection to the homebrew browser.
