I bought a new sound card: Creative Audigy LS. I installed it and WMP worked fine. I had to do a complete re-install of the card and drivers and now I get the message, "Windows Media Player cannot play the file because there is a problem with your sound device. There may not be a sound device installed on your computer, it may be in use by another program, or it may not be functioning properly". My card is working fine and music will play with the Creative Media Player. I HAVE CHECKED OUT THE SITE ASSOCIATED WITH THIS ERROR CODE and found it to be of no help in my situation. Does anyone know how to solve this?
