Internet works... but not for MSN Apps?

Hello,

I recently wiped my whole computer and reinstalled Windows XP sp2. After some toil, I got everything working right. Well, I actually had to buy a new Internet card to get my other missing drivers, as my drivers CD was not working (My old method of internet was via the motherboard).

So now I have everything working. Except for MSN applications like Windows Live Messenger, and Help and Support, which complain that I'm not connected to the internet... When I am! My internet works in all respects except for with MSN apps.

My network connections looks like this, if it helps:

INTERNET GATEWAY
---------------------------------------------
Internet Connection (Disabled) //When I try to enable this, it says it enables, but actually doesn't.
---------------------------------------------

LAN or HI-SPEED INTERNET
---------------------------------------------
Local Area Connection | 1394 Connection
(Connected, firewalled) | (Connected, Firewalled)
[D-link DFE-530TX+ PCI Fast Ethernet Adapter (rev. F)] | [1394 Net Adapter]



Anyone know why my MSN apps refuse to work through my internet card?

Thanks for any tips.
