Nintendo Wifi USB Connector Error WIth Firewall?

I just finished installing the wifi usb connector but now when i try to connect to wifi using a game it loads perfectly for the first part but then for the second part it says error:51029 or something like that. So i check it out on google and it says that its a security firewall problem. I have norton antivirus, but i dont know where or what to do to fix it. Can somebody help me out with this?

Here is what I got from nintendowifi.com :

If you wouldn't mind, I would suggest turning off Norton while going wifi. I also have Norton, and all I did was add the WFCRegsiter.exe program to my allowed list of programs. To do that, you need to:

1. Open up Norton

2. See if you can find "Option" and click on it.

3. Go to the list that says something in the sense of "Allowed Program". It's probably under Personal Firewall Configuration.

4. Add the WFCRegister and make it so that it's allowed.

Good Luck!
