First thing I would suggest is find the Java.exe file and right-click and choose Run as Administrator, alternatively choose Properties and set it to Run as Administrator from there. This seems to make a huge difference for connecting on Windows 7 or later.

Only need one firewall, as two usually clash with each other resulting in less security. Make sure LW is added as an exception.

This is the place where people come to report any problems with using LW, so yes you will see many related posts. LPE does have some bugs, but they can be worked around.

There is a chance your router is causing an issue. You could try port forwarding which is not that difficult. First thing to do is set up a static ip address: Setting a Static IP Address in Windows 7 - PortForward.com

Then see Port Forwarding Limewire on the Netgear WNDR3400 - PortForward.com unfortunately they use LW 4 as an example, instead you can see LPE's settings here http://www.gnutellaforums.com/tips-t...tml#post120010. After doing port forwarding, usually need to save settings and reboot your router.

Also, if you installed the LimeWire-Fix2, make sure you installed a fresh connection file after this.
