Purple Videos

Hi, i just got these vids (reviews/gameplay) to work but now i try to watch some and they all have a purple hue to them.  I searched the forums for a solution and found that i had to get the latest version of WMP, BUT I HAVE IT, i even reinstalled it but its still purple.  Imma try to restart my comp, and if it works i will post after this, but if i dont pls leave a solution or comment

thanks/
