MWS not working

[Liambic]

I've been out of the editing loop for about a year now, having lost interest in WoW for a time. I just got a new computer (XP OS, not Vista) and installed WoW and MWS, to find that my MWS won't pull up any .mpq files. I'm just trying to access the mp3s to see if any new music was added with Sunwell Plateau.
Anyone have any ideas?

I'm sure this has already been addressed over 9000 times, but I figured 9002 wouldn't hurt.

Either try the most updated version or use MPQ Editor.
