I recently built myself a new computer and ever since then WMP has not been asking for a username and password to play protected files off of websites. If I try to play a video that requires one it just says "Unable to access this file." Well how do I get the username / password box to authorize myself!? Thanks if you guys know anything!

Edit: Delete Me, I found out the answer. It was an option under the security area in IE.
