I am running LW 5.4.9. I have Windows XP and unable to connect. Im not ure if i did the port fowarding correct. i think this is my issue, can someone please help

Did you set up a static ip address before port forwarding? If you did not do it before port forwarding your router, then you will need to delete those port forward rules & do them again. You also need to set LW to port forward type of connection under advanced settings.

BTW I've never heard of LW 5.4.9 lol .. sure you have the version correct?

Also need to make an exception for LW in the XP firewall rules; Setting up an exception for LimeWire in your software firewall (click in link)

I tried to set up static ip address but im not sure if im putting correct numbers in - i did what exactly it said to put in but i think i am getting the dns server numbers wrong - they r different when i go through msdos and when i sign on to my router page

Setting up Static ip address for Windows XP. And for LW .. when you eventually actually install it to replace LW Turbo, don't forget to have the same port you port forwarded in the router also in the settings in LW: Manual port forward instructions & sample image

If in doubt about the DNS number, you could always call your ISP technical support & ask what it should be.

Oh .. the official LW download page is Lime Wire » Download LimeWire

Sounds like you're using "LimeWire Turbo 5.4.9", which isn't an official version of LimeWire. I'd recommend uninstalling it and installing the official version from limewire.com instead.
