Ok, I just installed Windows 7 Home Premium 64 Bit (fresh install / no upgrading from previous OS) on my system and so far so good except for an issue I am getting with Media Player. It plays all files fine on that are on my hard drive, however when I click on a link in IE8 for an MP3 or M3U I got the following error... The system is very clean with no other media players installed, no codecs, etc. I've tried everything I can think of to no avail. My internet is working fine, and I know the links to the files are valid as I can do a "Save As...", download the MP3 locally and get it to play. Any help would be much appreciated! Thanks.
