franco,

Did you uninstall LW because it kept on popping up all the time, when you didn't want it to (this is caused by a virus)? What you're experiencing sounds like what happens when you have this particular virus & uninstall LW.

See point 4 here for some info

Within that thread is a link to norbiesworld. If you go to his site & register (it's free), he'll be able to help you get rid of the virus. If you ever do use LW again, please scan files with your AV program before you open them
