You said WMP is your default player, what other players do you have installed on your com.
This is important due to play configuration.
I have a Toshiba Satellite A105 with Windows XP Home SP2. Recently, I tried the "Play all" function under "Music Tasks" in my music folder. For about 1 second, an hour glass appears but Windows Media Player (my default player) doesn't load. I have tried the suggestion at http://support.microsoft.com/default.aspx?kbid=322642 (although I never receive an error message, I thought I'd try it anyway). WMP will play the files if I select them individually, so there isn't any problem with my sound. I am only experiencing a problem when I try to "Play all" music files.
Any suggestions would be greatly appreciated.
Thanks in advance,
