For some reason when I am searching for music files now (this is the first timem I have had this problem since using for over a year) Limewire is pulling primarily WMA files, I only want MP3 and it is hardly pulling any!! Why is this happening and how can I get just MP3's?????

Put .wma in your keyword filters. eg: How to use the Keyword Filter

If necessary you can also do a general (all types) search & put your search like this: Artist - Title - .mp3

Oh & this FYI: What you should know about WMA/WMV Files
