Problems with my library on LimeWire

Hey, I just downloaded LimeWire last weekend and I've discovered a problem. When I download a file and it gets stored in my library; the name, the size of the file, type, and pathway is in red font (eg,*****, 3992 KB, mp3 and Documents and Settings... are in red) and the uploads, hits, locations, and license spaces are empty. There's also a grey X under the shared heading. Oh and when I attempt to change the song's name (to make it alphabetized for instance), an error pop up comes up and says Unable to rename '*****', It may be in use by another application What does this mean? The file still plays fine, I'm just a little concerned with why it's happening.

Thanks Remoc! I was afraid it was something bad, like a messed up file or something like that!
