i think i have the same problem but when i have to choose a hero i can ignore it and get a random hero ( so i dont need to reconnect)
but after 2 minutes i get a lag , a big lag(about 3 minutes) and sometimes later in game i get this lag a second or third time and so it is for me unplayable....
i tried to reinstall it and i tried out the european version too, same problem.
so i've got vista and tried administrator and install it into different folders... nothing works so i dont know where is the problem(on windows xp it worked fine)
so i need help
