As per your suggestion AvP, I'm now using uTorrent. uTorrent detects the seeders but isn't downloading any data yet. However, the whole reason I first tried using BitTorrent instead was that uTorrent always gave me fragmented files even when it was completed. The problem only came up after an update, and even though I changed to pre-allocate files, it wouldnt work. Do any of you have this problem?
Anyway, it is strange since I'm successfully downloading other MySpleen torrents fine on BitTorrent...
However, thanks for seeding! Hopefully I can fix the problem on my end.

EDIT: All right. uTorrent is now giving me data. I'm at 17.8% and downloading at a low but consistent speed of about 4 kb/s. BitTorrent still doesn't work, and I'm hoping that uTorrent won't have the "fragmented files" problem...
