Hi,
First try lowering the security level of your browser to Medium, then check your antivirus or internet security programs to make sure it is not blocking the connection, or in some programs you may need to add limewire to the safe sites. You can also try disabling these programs to see it they are causing the problem.
Hope this helps. Let me know if you have any questions.
