I ran into the same problem as well. The downloads just 'start' but, in fact, they never do. Also, I get the error message saying 'Error saving hash data. Access is denied'. All this happened when I installed the new 1.2.0 Beta version. I've just reinstalled the stable one (1.1.0) and it all works fine again. I guess something is wrong with the new beta. Hope this helps :)
