If you are running windows defender you have to go in there to fix your fire wall problem. You need to go to my computer, c drive, program files and click on windows defender. Click on the fire wall which is MSASCui. Then click on tools, then options. scroll down to default actions, and click ignore on all 3 alerts. Then click save, and thats it. close out and try connecting to lime wire. I just did this and now I can connect. Good luck. I have been working on this for a couple of days, and I was ready to delete the program. Now I don't have to.
