Nette505,

Double check that your Windows firewall's still configured to allow LW.
User Cant Connect - LimeWire

Have you been able to connect since updating to Java 1.6.0_02? People have had trouble with that update. Try this version instead. Use the JRE offline installer & remove your current Java version before you install this one.

If that doesn't help, delete LW's preferences folder when LW's properly closed. See point 3 here & also point 2 if you've used older versions of LW in the past (there could be a folder in either location).
Fixes for LimeWire
This will kill all of your settings within options, you'll have to go back through afterwards & reset things. If you're not sure of your settings, go through LW's tools > options & write them all down, so that you can reset things later.

Your modem doesn't have an internal firewall. Are you using a router as well? If you are, please tell us the brand & model


cain-marko,Start off by changing Java versions & also delete LW's preferences folder...just see the instructions I've posted for Nette505.

You could also double check that your Norton firewall's allowing LW...even reconfigure the firewall. These 2 links should help with that.

PortForward.com - Free Help Setting up Your Router or Firewall

If you still can't connect try port forwarding for your router, that should get rid of the firewall icon & (hopefully) help with your connection. The instructions are here.

Don't forget the step of setting up a static IP address first. Don't panic when you see those instructions...they're a spin-out at first but all you have to do is follow them step by step & you'll be fine.

Just remember that LW's listening port, port in the 'manual port forward' box in LW & the port forwarded within your router all have to be the same number. Otherwise, things won't work
