This has been a recent complaint by a few people. Not sure why unless it involves some type of virus or something. Did you get your LW from here?: http://www.limewire.com/english/content/download.shtml

You can try deleting your LW Preferences folder whilst LW is closed; instructions here: Fixes for Limewire & see if that helps. Remember to make a note of all your settings & locations of downld & shared folders before you do this! 8,k
