i had the same problem with my limewire. it wasn't letting me into the settings, and it would re-open every time i shut it down. i uninstalled limewire, but i also had to go into my program files on my C drive and remove the limewire folder and empty my recycle bin. i had a problem doing that at first because i kept getting an error message about limewire trying to start. i had to be quick closing the message and deleting the files as soon as the message disappeared.
**remember to empty recycle bin after deleting folder**
