You still can't get into chat? I know there is archived info regarding the basics, but I have no way of knowing what you've tried.

Have you gone into your internet connections and properties, network and advanced buttons? This might also be accessed through your START menu...CONNECT TO... slightly different settings there.ADVANCED: Your firewall for one.

Have you gone through your advanced settings and clicked on mostly everything? The only things I don't have clicked/checked off is notification of every script error (not) and certificate revocation (not) and I don't force offscreen compositing.

If you have any anti-spy programs, or other programs that you downloaded while you were on PC or another type site, it might be messed up and not allowing here.

If you have McAfee or Norton... that might have an additional firewall.
