getting my station to work

[qcam0707]

Hi all. I have been trying for days to get my station listed. I keep recieving the Nak error message that it seems like many have gotten. I have tried everything, I completly disabled my firewall, restarted my computer, and router, turned it back on and got the same message. Also I tried switching the yport to 666 instead of 80, with no luck. I am using WindowsXP. I would appreciate any information or tips anyone can give me. Thank you!
