Sorry Mac,that I didn't include that information when I posted my query.

I'm running Windows 7 (Professional) on HP Compaq Presario, and yes I'm running as the administrator. I just get so frustrated when I've run every fix that windows has for sound and nothing fixes. One fix did tell me I had some corrupted files but not what they were or how to fix them. I've come to hate Windows Media Player because when someone sends me a music file and I download it, it goes directly into Media Player and I can never again find the file. And there's no help button to push in Media Player.
I'm about ready to junk it! I've been searching Microsoft forums looking for solutions too.

The last message I got just said: Couldn't open wave device...the likely cause is that another program is using the audio playback or has left the driver open. The only two programs I could think of would be Media Player and BIAB that I have been using. I've been working on this all day and getting nowhere.
