It's a little weird that it's 1/3.

Let me explain how it works. It sounds like you have an older system, so this greatly affects you.

Before a file can go into the library it needs to be scanned by Limewire. The scan will take longer if the files are big, or if the computer is an older, slower system and if the app doesn't have as much RAM as it could.

Solution: Wait. Just leave limewire on for a couple hours or a day or so (if possible) and all those files will eventually load into the library.
