So, I downloaded the new WMP 10, however, it won't let me view some mpeg files. I sent the same files I'm trying to view to like 5 of my friends, and they can view them all fine. I went to the Windows site to downloaded the "codec pack" which I'm assuming is what I need to do. It said to enter a 25 digit key from my COA...which I don't seem to have anymore. There MUST be another way to get the codec, isn't there? All I wanna do is watch my movies!
