When I installed a previous version of Limewire, during the scan for files it discovered some directory pointing to an external back-up CD that I had made. Now each time I launch Limewire, it asks me to insert this disk. I have uninstalled Limewire and removed every visible file I can think of. I have then reinstalled a new version, but I continue to be prompted to "insert disk..."

Is there some invisible file(s) I should search for? Any ideas?
Thanks!
