Does Peerblock also prevent me from downloading torrents?

I know what it's for and everything, but I'm pretty new to downloading torrents or anything (and before you harp on me about downloading - I'm only doing this as a last resort to get some very early Matthew Good songs that I can't even find versions that I CAN pay for) and I got peerblock just to be safe. I started downloading one torrent before I got peerblock, it didn't have many seeders but it started to download just the same, and then I got peerblock and started downloading a second torrent which says it has more seeders, but now there's no activity on either of them. So I'm just wondering if peerblock has anything to do with that? My brother says his torrents always download pretty fast, but mine haven't budged at all in the past three hours... any help would be great.
