looks like you're missing xsd (xml schema definition) files... limewire uses those to know how to read metadata. they should be under <limewire installation directory>\lib\xml\schemas.

if they're not there, i'd recommend uninstalling and reinstalling the latest version of limewire. if you're feeling adventerous, you can even try out the latest beta (2.8) which has some nice improvements. see adam's post here for more info.
