BitTorrent update now really slow speeds?

I have been using BitTorrent for years and reaching speeds up to 4Mb/s on some downloads, never anything below 1Mb/s and since I did the automatic update today, the speeds can't seem to get past 200kb/s! The torrents are good as I usually pick, tons of seeders and the only excuse is the frigging update as everything was fine yesterday!

I am running on my MacBook and using BitTorrent 7.3.5 (now)

What can I do?
