is it u got dc within secs the moment u login to server?
cause i got friends using vista they run the game very smooth, even
smoothly than me ( XP user )
that time i d/l manual patch, after finish i login to server, keep
on getting dc within 0.2 to 3 sec upon login in to server
then i uninstall the whole client, download the latest whole client
and reinstall the whole new client again, voila! it's done, problem
solved
