AFAIK Add/Remove programs is not the way to uninstall the present version of LW. It might have only partially uninstalled it. (BTW the normal process to uninstall LW is Start menu>Progs>LW>Uninstall.)
1. Reboot your computer or else, Control+Alt+Delete & bring up the process manager. Find Limewire on the list & kill the process.
2. Download Java:
http://www.limewire.com/english/cont...radejava.shtml (preferable to downld installer to your computer & then install it. Not to install over the net!) Then install Java.
3. Install LW.
