Issue there is that you can't uninstall LW using the add/remove control panel. At least you will only partially uninstall it. The normal way to uninstall LW is Start menu > Programs > LW > Uninstall. But there's also a uninstaller in the program folder. Also, re-installing LW will remove the previous version at the beginning of installation process. So I'd suggest you reinstall it.

Also, I'd recommend you remove all versions of Java you have using add/remove control panel. Then reinstall using the "Offline" Java installer which is about 15 MB downld; Java 1.5 (take the JRE) I would recommend installing Java BEFORE reinstalling LW!

It might also be worthy to delete the LW preferences folder before you reinstall LW; Point #2 & 3 in Fixes for Limewire (sample image included at bottom of page.)
