Well you could try a couple of different things.
Check out PeerGurdian2 and see if that works for you.
If that doesn't work you have one other option. Since you can still access thepiratebay and demonoid you could copy the tracker url then create a imageshack account. Within the imageshack account they have a free 5GB torrent drive.
You can copy the torrent url into the bar and have imageshack download it to their server. After it is downloaded you can then download it directly to your computer through imageshack. I highly doubt your isp would block imageshack downloads from you. The only thing that sucks is with a free account you have to wait for available bandwidth but overall it will be much faster once it's on imageshacks drive for you to download.
EDIT: Looks like they charge for all service now. You used to be able to get a free 5GB per month but now it's $3 unlimited 1 day, 10 GB $10 month etc. Check out there rates.
I guess you could also use a rapidshare search engine too and just download from that. Most torrents end up on a rapidshare account somewhere.
