linz321,

What fixes have you tried (that haven't worked)???
It's not a good idea to run 2 software firewalls at once...they'll interfere with each other & you'll end up being less secure Pick one firewall, configure it to allow LW & turn the other one off.
Look at my post #8, delete the preferences folder & change Java versions. If you decide to update to the latest Java & can't connect - try that older Java instead! Deleting prefs folder & up*******changing Java are 2 fixes that often work when someone starts having problems out of the blue.

Your ISP is the company that you pay for your internet access (eg Tiscali, Pipex, Virgin). Who is yours?
Do you have a box with lights on it that plugs into your computer & lets you connect to the net? If so, have a look for brand & model.

kaos0051,

Same deal for you as for linz321...choose either McAfee or Windows firewall. Not the 2 together.

Make sure that there's not a Windstream firewall causing problems. Check the thread below

In LW tools > options > advanced > firewall config. Change LW's listening port to 64049 (or you can try other ports in the range of 49152 - 65535) > apply > ok. Restart LW & see if you can connect.

Your Java version's a bit old. Update to one of the versions linked to in post #8.

If UPnP's enabled on the Siemens, try port forwarding instead. If the fixes above don't work, go to the site below. Find your router model, click on that & then choose LimeWire from the list of programs...you'll find step-by-step instructions for setting up port forwarding.
PortForward.com - Free Help Setting up Your Router or Firewall
If setting up a static IP's part of the instructions, don't miss that step. LW's listening port, port in the 'manual port forward' box & port forwarded within the router should all be the same number.
