How do you put music in your mp3 using Windows media player?

My Windows Media Player Won't Open?

• First off, my computer is a Sony Vaio running with Windows Vista. Now for the problem. For the time I've had my laptop, which is about a year, I've had no problem opening Windows Media Player until a week ago. I was working on my music video and I wanted to see if the green screen worked so I rendered it and went to open it up with Windows Media Player, but it wouldn't open. I thought it was the same problem I had with iTunes a few weeks before that I just need to restart my computer and everything was fine, but it wasn't the same exact case. I restarted it, and it still didn't work. I waited it out for a day or so, and it got annoying. Finally, I resulted to searching the exact title of my question, and nothing seemed to work. The thing where you go into Command Prompt doesn't work, and I can't reinstall it. I can open it when I run is as an admin, and only play the music/movies I have in there already. What that means is I can't put anymore music into it, or open an mp3 file or any file with it. Also, all my music I have is in iTunes Music Player format now and I don't know how to change them back to an mp3 format without using a converter. If anybody has a solution to these, that would be great. Please explain in a simple language because I'm not that good with computers. Thanks for taking your time and reading this.
