I had a very similar issue, i followed some instructions from the forum and cant remember where. In general i had to down load both Java and limewire to my desk top (do not load from site) delete the lime wire folder, uninstall java all versions and uninstall limewire, disconect from internet and load both again. it worked until my daughter put a new skin on then did the same. i went through it all again no new skin and working fine.
