>I changed some settings of the WMV file extension yesterday on my PC and now, from IE, when I have a WMV file I need to access, it starts downloading it instead of playing it by streaming it. Anyone would know what I have to do to fix that?

Interesting. Usually people are trying to figure out how to do the opposite (download a WMV file instead of have it stream)... anyway - are your .WMV files associated with your media player?
