I was having some graphical problems, and nothing was helping. After uninstalling WoW and reinstalling it, and waiting for everything to be fully downloaded, it says "Unable to connect" after I enter my username and password. However, when I first opened WoW after reinstalling it, it let me connect, but upon attempting to change servers to Emerald Dream, nothing would happen. After closing out the game and reopening it, it just gives me that "Unable to connect" message. I've tried everything on the Support website, but nothing is helping. This has never happened to me before. Any help?

Apparently it's not my computer, it's a big thing that started happening about 2 hours ago at the time of this post...anyone else experiencing this?

I haven't had any problems.
