The ATP website hasn't worked properly for me in a couple of days now. I'm not even being told to download anything, the screen is just messed up with a weird list of tournaments and random images spread around a blue page.
Whichever browser you are using, try a different one, and if that doesn't work try the original again. This happened to me a few days ago: I use Firefox, but tried IE. I still had the same problem but when I went back to Firefox everything was ok
