Yes! Did you look at the 1st link I gave (point 1)? lol
BTW did you delete your LW prefs folder? I believe that is a part of your problem. LW will download partials of updates into the LW prefs folder. So it speeds up updating. But with the older ones still there if you didn't utilise them, then that may be causing your problems.
Oops ... looks like my reply was slowish!
