If you removed java from your system LimeWire won't work. LimeWire requires java to operate. LOTR has put a link that has the java links.

In windowsXP start>control panel>add or remove programs --- see if you have a program called J2SE Runtime Enviroment 5.0 Update 4 or something similar.

If that is missing you do not have java installed, and need to install it for LW to work/run.

It is also possible that the java for some unknown reason may have been corrupted. You can remove from the add or remove programs, and try a fresh installtion.

Just follow the instructions in the link LOTR left in his post.

I suggest d/l the offline installation version, if you need to reinstall it.
