First your not supposed to double post, it's in the rules. Second people are reluctant to respond to posts asking for help with "porn" you could have left that part out. It wouldn't change the answer.

Now it sounds like you need to d/l codecs for wmp to play your files. You should also consider getting a second media player to use, at least as a back-up. VLC media player is a good one with the codecs built in and will play most video files. For more info go here: CODECs list for Movies /Alternate players / Video help forums

Edit: fyi check out this thread: What you should know about WMA & WMV Files
