yeah the Chinese client version installed for me without issues, changed it to EN for my EU location, worked too, started installing the game and it downloaded with 80 kbp/s , then went up to 5 mb/s ( i have gigabit internet) then back to 50 kbp/s. It keeps jumping back and forth, sometimes up to 15mbp/s . Just keep trying boys, eventually it will come back, but its really a shame that we have to go thru all this to get our games etc…
edit: HERE IS THE LINK FOR SAID FIX THAT HELPED MOST OF US.
edit 2: yeah I agree its insane that we have to deal with all this without having confirmation from Blizzard that they have issues and they are working on it, nobody has to reset their whole systems etc…
