I've tried publishing the map I downloaded (Hell td 0.22), but it said "cannot publish".. It was due to an error that had no explanation.
Edit: Got it to work!
So how does one play them ON battlenet? I want to download and play Hell TD 0.22, but Bnet only has 0.21. There is a download on here, but I dunno where to put the map, or how to launch it. I wish to play it with a friend on Bnet, not alone.
