the five torrents per page thing, it's really starting to piss me off.
For this, you can click on the "Recent Audiobook" heading on the right. Then you get the torrents in plain list, about 150 torrents per page.
Otherwise, I just tried and could download ten torrent files in a row.
Maybe a temporary problem.
Look at the address bar: sometimes you get sent to abbproxy.com, instead of audiobookbay.cc, which looks the same but your cookies won't match and you won't be logged in.
In that case, back up or manually change the URL.
