Connecting online

Can someone help me? I just bought NL2005 and i cant seem to connect online. I have a network adaptor and everything seems to be running perfectly. However when I select online play the adaptor disconnects me and a pop up says that I need to check my network configuations.

What steps are involved to connect online?

I play Hot Shots Fore online and it works perfectly fine.

Thanks

you may wann check and see if your compm is rejecting the connectionand blocking it.
