There is an old movie I want to find, actually a tad of film history, but anyways...previously I used the PMFACT application, which has it's own Torrent client (ACT.EXE) on a couple of occasions, but that was a very long time ago and I maybe downloaded a total of 1 or 2 things that way. 
Well, trying to do this now produces a repeatable SYS3178, which appears to be a divide-by-zero exception:

I did install CTorrent, but PMFACT will not co-operate with it, it throws a VREXX exception, so the only option appears to be the provided ACT.EXE.
So off I went searching for things and came across QBitTorrent. Installed fine, was thrilled to see that. I tossed my .torrent file at it...but the STATUS simply shows 'Stalled'. Some more digging around (yeah, lol, as you can tell I am definitely NOT a Torrent maven) and I located an updated Nov_2017 list of trackers, added them to my install...but I do not actually see the app connecting to them.
It also appears like the QBitTorrent uses a separate Tracker list for each torrent...

Therefore, I'm curious: what is everyone else using?
