I had that problem when I was on a wireless home network, as soon as I went back to hard wire connection it worked fine again until today.
Not sure, but I may have forgot to switch my flash back to 8r24 a few times while on that wireless setup, so not entirely sure if it was the problem or not.
konfoo, it seems pandora mucked things up again today or last night, pandora rip isn't working at the moment.
