She could update her Java using the
offline installer (the latest JRE is update 9). There's a link in point 1 of this thread...
Fixes for LimeWire
She should remove her old version of Java (add/remove programs) before installing the new version.
She could also delete her LW preferences folder when LW's closed. That's points 2 & 3 above. *The prefs folder's hidden, so she'll have to view hidden files & folders to be able to see it.
Then she should reinstall LW but make sure to use the
offline installer.

Uninstalling LW through add/remove programs is not the way to do it. This can cause problems. The way to uninstall is via start > all programs > limewire & then click on LW & use the uninstall option
