Is anyone having a problem downloading the new patch? I get about halfway through and it says "The tracker is not responding?"

Titantlaloc,

You may need to ensure ports 6881-6999 and 3724 for the TCP (also called TCP/IP) protocol are open in order for the Blizzard Downloader to connect correctly. If you are using a router, you may also need to set up port forwarding for these specific ports as well. You can find further information on how to configure firewalls and routers on our Networking help page - http://www.blizzard.com/support/wow/?id=msi0423p
