Now were getting somewhere.

I have never had it on and am not going to try it either. if there is no option to disable it (try reverting pop-ups to default if there is no other option to do this) If that doesn't work either then

Delete Limewire preferencefolder while closed. (.limewire) if you can't find it use search on forum

Then when youre asked on setup if you want to use contentfiltering say "NO WAY"

That may very well be the root of your problem
