Hi since this afternoon (2/10/07) I have been unable to connect to any servers on Halo Custom Edition or even Create a Lan server which I was able to do like yesterday and this morning. Its not only Halo Custom Edition its also Command and Conquer Generals. However America's Army works fine. I disabled my firewall and AV but still no luck. The weird thing is I can see the server list and see the stats but not connect to them, I can still download & surf the internet.

OS: Windows Vista Home Premuim
CPU: 2.0 GHz

Modem: D-Link G604T 
Modem Firmware: V3.00B02.NZ.20060711

The games worked fine until this afternoon (they have been working fine for the last couple of weeks)
