If an accident happens...

I remember another user telling about HitFilm crashing his computer, but I couldn't find it, so I wanted to confirm: If you already purchased and downloaded HitFilm, and something happens to your computer, is there a way to re-download it for free, no strings attached?

Yes. Once you have registered the software, it is available through your account on the site, any time, all the time, whenever you need it. In fact, since the demo uses the same installer, all you need is your serial number in order to re-activate, which is available through your account here: http://hitfilm.com/account/software
