I thought sourceforge was reputable - is there something I don't know?
Very likely. There's undoubtedly a great deal that the majority of us don't know.
...reliable/reputable download site - one that actually works...
Well, the context is that it needs to be "reliable and/or reputable", and not forgetting the "...that works", and I got seriously frustrated with trying to get it to work, and eventually gave up, as I said. And this was the 2nd time.
Maybe ABP or NoScript were blocking stuff, I don't know. Or this FF ß is probably playing up. But I tried IE11 as well.
All I wanted to do was download the blasted file, not go through a third level problem analysis and resolution. Again. Sheesh.
And I've got acute bronchitis.
