I've gotten the 'banned' message several times, over several days. So it doesn't seem to be the page or file I'm trying to download. I'm using Google Chrome browser. But just to check, I used IE8 also - same 'banned' message. It may have no bearing, but when I get those messages things aren't looking so hot on the beta --- slow slow responses, or lots of images are missing.
And once I get the banned message, I have to wait a day or so to get 'unbanned.' ?
Other than that, this beta site is a HUUUUUUGE improvement over the older one. I'm lovin' it.
