removing DRM(i think) protection

I have downloaded a bunch of videos from a website in .wmv format. When i play them a box pops up and asks me for a username and password. Is there any way to play these files without this box popping up?
Thanks!
Answer #1
Did you check if your infected ?
Answer #2
no no i’m not infected this was a private forum so they didn’t want people to share videos, so you need to post your log in info for the site when you try to watch the videos. I have a username and password so i can get the license keys but i only have it for another 3 days!
