Ouch!

Not good. I thought the .torrent.sd thingy simply was an extended version of the .torrent file type. Oh well.

Luckily for you, I found a topic that is relevant on Shareaza's forums : Guide: Recovering or Continuing a Shareaza bt download in another bt client - it seemed detailed enough.

Good luck!
