If you dwnlded a file with a .wmv extension then anything is possible! That's M$ for you. They have incorporated a licencing system that is incorporated within many of their files. Some of these request connection to a site. This also makes way for this portion of the file to have been replaced with a request for an alternative site. M$ are so dumb it's unbelievable. And I thought my IQ was small! lol
Well I think my brain is getting smaller but M$ are getting dumber by the update.
I would delete any such files that you may have dwnlded either purposely or accidentally. Also I would add .wmv, .wma & .jpg to your keyword filters. ie: LW's menu Tools-Options-Filters & keyword. Don't forget to press both the Apply & OK buttons after.
Are you sure a wmv file originated from LW or another source.
