Since last night, I've been trying to install the US client since I have the WOW annual pass. My installer file will just finish updating set up files and then Launches the Blizzard Launcher but nothing happens. Yes I tried every solution posted here including Secondary Logon one. Just now and just for the heck of it, I tried downloading the EU installer and it works just fine , it's began downloading game which is now at 25% or so. Will I have any issues running the EU client even though Im in the the US?
