Are you seeing this error, but LW works ok in between errors showing up?
Or...have you uninstalled LW but this error pops up anyway???

If LW's still installed:
Have you had any problems with LW not connecting or not opening, since you've been using Java 1.6.0_02? If not, try reinstalling that Java again. Download the JRE offline installer & remove your current Java version before you reinstall.

Some people have had probs with that latest Java update (works fine for me though), so if LW's been misbehaving...you could try this Java version instead. Again, download the JRE offline installer & remove your current version before installing this one.
