Suddenly - Shoutcast wont work from Winamp. Can you help :(

[KatanaDV20]

Hey guys could you please help out with some advice this has defeated me. Ive been listening to Shoutcast from inside Winamp for the last year without issues.

Today out of the blue:

Internet connection is solid, all other streaming sites that I use work fine (YouTube, Vimeo) so why is Shoutcast going legs-up

Any guru advice welcome please I cant do without weekend trance & tech house

Thanx
