Delete the shared and incomplete folder along with the limewire folder you unziped. Open a terminal and type,

sudo unzip -u LimeWireOther.zip -d /opt/
sudo chown -R root:root /opt/LimeWire/
sudo gedit /usr/bin/runLime.sh

Use gedit for gnome or kedit for KDE.
Insert the following lines into the new file THEN SAVE IT.

cd /opt/LimeWire/
./runLime.sh

Again in the terminal type,

sudo chmod +x /usr/bin/runLime.sh
sudo gedit /usr/share/applications/LimeWire.desktop

Again, sub kedit for gedit if need be.
Insert the following lines into the new file THEN SAVE IT.


[Desktop Entry]
Name=LimeWire
Comment=LimeWire
Exec=runLime.sh
Icon=/opt/LimeWire/LimeWire.ico
Terminal=false
Type=Application
Categories=Application;Network;

Look in your Menu / Internet and there it is..
Hope this helps you out.
