I had the same as you, Sam, it's changed now so it's downloading as I speak. Think is it's topping out at 3.2kbps (mostly 2.2) and when I load any pages or anything then it stops entirely. Even as I type this it goes on and off. It's gonna take some time, I reckon.
When it wasn't working I tried changing the link that was in the button from within the address bar, but it gave me a 404 error, but then when it worked it had exactly the same link as I typed in, which is the same as you posted, Jase.
Crazy stuff!
