Thanks for the replies and advice Dan and Pottel.
I thought about changing clients but then decided to remove/reinstall BitTornado. It seemed to work after that. I let it run overnight (well, 6 hours) and this morning it was only 10% downloaded... with horrible upload (0%, no other leeches but me, I guess). I'm letting it run today but if it's not going the way I think it should by the time I return home tonight, I'm considering bagging the whole thing, downloading utorrent and trying again.
Right now I have that horrible spanking icon on my account b/c my ratio is so low. I feel terrible about that!
If I restrict my download speed, how long will it take to download a typical show? I don't mind slowing it down, but I don't want to be downloading for 5 days, if you know what I mean.
If anyone else has any bits or bobs of advice, I'll gladly take them. This is all so new to me.
