dont change your settings too much you might screwup your internet connection. All you should have to do is make sure your modem is on and that you are indeed connected to the net while in Limewire. what do you have for a internet provider? Are you in windows? what version of Limewire are you running? If all else fails for you try to do a clean install of Limewire. I dont advice you to open up ports because that allows for hackers to get in your computer system. you shouldnt need to do all that to get Limewire to run.
