The correct way to uninstall is Start > All programs > Limewire/Uninstaller

Use your computer's search to look for all files & folders with limewire in the name. If you can't delete them, reboot into safe mode & then try. If they still won't delete, try one of the tools here...
Incomplete Download File won't delete at all.

Now that Limewire is completely off you system you can now re-install it using the offline installer...To find the offline installer, use the link below > cancel the installer window when it pop's up and then select the offline installer link...
Lime Wire » Download LimeWire

If your a Pro user just use your personal download page....
