Rhonda, Are you in College?? You say that your in a Dorm. Well, I have to give you a "F" on answering the questions. Internet Explorer is an Operating System, not an ISP. The reason why you can't connect is because you have a Firewall issue and if you are at college, it may be next to impossible. Ask around to see if others are able to connect. The school is probably blocking P2P.
Also Vista + Zone Alarm is a bad combination for Limewire.
Try uninstalling both LW & ZA, then reinstall LW first. After that, reinstall ZA. This has worked for a few Vista users...see post #6 of this thread
Can't connect using Vista.
Also it's not a good idea to have 3 Firewalls nor is a good idea to disable them, instead figure out which
ONE you want to use and give Limewire Full Access.
Need to also know what version of Java You have.
Hope this helps.
