You should ask Blizzard Technical Help, and not here. We can't help you with your connection problem to Battle.net servers.But problem is i have a problem with the internet connection to download maps from Blizzard using the method taught by you.
You'll want to try changing some settings in the Players Properties, making some of them Computer. If that works, then you're good to go.Can I download maps and open using World Editor, then use "Test Document" to play the map ? (I have tried that but because there isn't any "AI Plyaers", I immediately has "victory" when the map starts. Is there a "melee" map or maps that I can download and use this method to play ?
