I was using utorrent, and it was indeed 100% complete.

It's a good thing to check, a pretty good thought, of course. However, I have been torrenting stuff for more years that I'd like to think about with reasonable success (yay, install media ISOs and the like). I'm pretty sure that the torrent client thought it had the contents of the torrent, that it was complete and had been seeding for a while when I stopped it.

BTW, I tried updating my utorrent (it hadn't been used for a while), and AMAGAD, suddenly it was horridly spammy and groaning with adverts, so it has to go :)

I'd probably use qtorrent or something, when next I try. The only issue is that I can't see the torrent on myspleen (or anywhere else) atm, either. If I could find a viable source, I'd probably start again from scratch, if needed.

Edit: myspleen's search seems to be showing it again, so I will have another go, if it looks right :)
