There should be nothing to download before launch “Heroes”, all preparatory work on loading should be done by the battle.net client. After all downloads completed button will be enabled, what a difficults? Why does some strange dialog appear and download data with speed 50-200 kb/s? Dialog can be hidden at launch and it will seem that the heroes unresponsive before launch.
Hi, I haven’t had this issue before, but now that I started playing again and there was an update to download, this window pops up as descriped and now its about 1,8GB with very slow dl rate. Is really annoying.
