2GB.com - Cannot Listen To Streaming Radio anymore

[Dasha]

Hi my problem is not recording so much as I can no longer hear all my Australian "Commercial Radio Stations" via Streaming with Windows Media Player or Real audio? I just installed Firefox and Gmail don't know if that is a clue but they were all working yesterday. I can listen to their Podcast's download and save them" but not "Streaming Live. The 'Listen Live pop up window' of the Commercial Radio station pops up but nothing happens, just a sign saying "Waiting for Video"? could I have lost some Codec's or should I install new ones? I must have done something as there is four different stations that won't play including ABC Australia 2GB Sydney, 3AW Melbourne and 4bc Brisbane.Any advice would be appreciated. thanks Dasha
