Dont know if anyone can help. One of my favourite bands (Span, top Norwegian rock band) have 'released' their new single as download only. I have downloaded it, upgraded to Windows Media Player version 9 but when I try to play the file I get the message The required security upgrade cannot be validated. Try installing the latest Internet Explorer service pack. To install the service pack from the Windows Update Web site, click Web Help. I have followed the link and downloaded all the upgrades but it still doesnt work. Any suggestions?
