if they're using the same tracker, getting the torrent from a different source won't help..

It could just be that you're having trouble routing to gotwoot for one reason or another. Have you done the microsoft two-step (shrug, reboot)?

Usually "problem connecting to tracker" comes with some other info -- like "connection timed out" or "connection refused" to let you know what happened. I am not sure if ABC gives you that info or not, but if it does it could be helpful.

Is the problem still persisting? It seems like you said something along the lines of "other gotwoot torrents work, but these don't" -- is that correct?
