ive just downloaded limewire and ive tried to download music and films but when i go to preview them it comes up with windows media player encountered an unknown error c00d11cd.so i dont know what to do,can any1 give me any advice please on how to sort it out..

My advice is to go into Tools, then Options, then Player and tick the box saying 'Use Limewire Media Player'. You shouldn't get any problems that way.
