EDIT: antivirus is off btw

1. cata realms on Warmane have been shut down

2. if you tagged this post Cataclysm by accident, it looks like the streaming server used by the "download as you play" client is down, so it doesn't know where to get data from

Is it possible to change server without downloading other one
