Game starts doing a patch, stays at 0%. Then this happens "Patch Required. Press the restart button bellow to exit world of warcraft and download the patch." when I hit the "restart" button another message appear, "Failed to apply patch. Please try again later. If this problem persists you may need to reinstall or contact technical support." I already reinstalled and it keeps doing the same. I played with friends yesterday and today none of this happened to them. What should I do?
