I've had that very problem this morning for some reason, I couldn't even get on to FM from a google search, very strange. I finally got my son to send me the link on MSN and it worked fine so I replaced my fav links with it and it seems ok now, very very strange.
I ran Adaware as well in case it was some sort of spyware or trojan thats caused it and if it is maybe its coming down off the actual site, strange things happen on computers.
