Jep, you've been scammed.

Due to the current P2P crisis I'd like to point out ukbobboy01's note form the 8th page of the thread that LOTR gave you:

Everything the scam site told you were lies, that means everything you thought you were downloading legally you were downloading illegally.

BTW, the official BitTorrent website is www.bittorrent.com and it contains no banners or whatsoever.
