tsp : if you're refering to deleting LW's prefs, see here: C:/Documents And Settings/your_username/.limewire You can simply use your search function (bottom-left & press Start & select Search) & find .limewire You need to delete the folder (.limewire) before restarting LW. But you must do it whilst LW is closed & make sure you remove the icon in the task panel on the lower right corner before you delete it. Then restart LW (will need to reset options) & things will hopefully be fine. If not, post back in detail about your firewalls, modem-router brand & model, Java & LW versions, & where you are trying to connect from (home, school, work, etc.)
