When I click on the Download midi link (or play button) on a page like this one:
http://www.8notes.com/grooves/show_groove.asp?groove_Id=1350

Windows Media Player opens up but then I get an error message and the midi never starts to play.
Error: "Windows Media Player cannot play the file. The Player might not support the file type or might not support the codec that was used to compress the file."

I am using Internet Explorer version 7 and Windows Media Player version 11.

Please help, thanks!

Also I am using Windows Vista

I have the same problem with the groove generator only. Other midis will play in the internet explorere window without the media player opening.
