Did you uninstall LW using the Add/Remove Control panel? If yes, that's the reason for the problems. Reinstalling LW will normallly remove the previous version. For uninstalling, Start menu -> Programs -> LW -> Uninstall. The uninstaller is also found within the LW program folder.

Try these things & in this order:

1. (a) Remove all Java versions. ___ (b) Reinstall Java using the OFFLINE java installer: Download Java software from Sun Microsystems

2. Try deleting your LW Preferences folder whilst LW is closed; http://www.gnutellaforums.com/genera...der-vista.html
