I have Vista and have been successfully watching movies with Sky Player. I have also been watching programmes with 4OD. However, today they have both stopped working.

I can download the movies/programmes fine but to watch them with streaming is impossible.

They open up and all I have is a black screen which says buffering. Before the buffering part would show a percentage that was buffered but now it just kind of freezes on buffering and won't start playing anything.

I have already tried unistalling & reinstalling and also doing a system restore with no success.

Any suggestions on what could be wrong would be greatly received, thanks!
