Theres got to be some kind of application data or preferences folder, when you do your search just use the word limewire and see what all pops up. worst come to worst, uninstall limewire do your search, delete everything that says limewire, then reinstall lime wire. It's been working for almost everyone that used to have no problems with limewire.

In Windows Vista to enable viewing of hidden files in any windows folder click tools > folder options at the top. click on that and then view then show hidden files and folders. it is at C:\Users\name you use to login\AppData\Roaming\Limewire It MIGHT also be at C:\users\myname\.limewire Any confirmation of where you find it would be welcome This seems to depend on the version of Limewire you are using.

this will have to be done while limewire is closed. after the folder is deleted restart and then open limewire
