Delete the LW prefs folder. Search your computer for limewire, see how many program versions exist. If LW 4.16 exists then is it in a different location to 4.18? LW 4.18 should have removed the previous version at the beginning of the installation process.

Use the Start menu -> Programs -> LW -> Uninstall, option. (May need to do this twice.) ! Then use either or BOTH _ Crap Cleaner _ & _ Microsoft Windows Install Clean Up to clean registry. Then reinstall LW using this OFFLINE installer: http://www9.limewire.com/download/LimeWireWin-full.exe
