I know that LW is supposed to install over the old version, but mine wasn't doing that properly. The older version was corrupted. I did a system restore, and took it back till I had an uninstall, and then uninstalled it properly. I then re-installed the new version over a few files left in the old folder and its working beautifully. Maybe I made a mistake by downloading the installer to the Limewire folder in the Program files - do you think?
