I've been fighting all night and now four hours through morning to get HitFilm back working. Kept getting a grey, then a blue screen hang. Uninstall, reinstalled x2. No deal. Did system restore, did a registry clean, you name it I did it. Finally, I right clicked the install .exe after the third clean install, and, instead of choosing repair, I chose Troubleshoot, and Windows set it to compatibility with Win8. Now it's working again. Don't know what happened, but I'm telling you that this was a VERY unpleasant experience, especially since I'd just been using it not a half-hour previous to it crashing. Just an FYI post, kind of hoping that somebody around here can tell me WTF happened. I have auto-updates on Windows 10 shut to Business level/Critical Security Updates ONLY to avoid MicroSoft-in-the-Head's "try-it-on-users-to-beta-test" BS, but I'm about ready to shut all updates down. I haven't been warned of any updates, not that they'll honor that setting, but, geez. This is not a fun game, at all. Any thoughts on what happened to my HitFilm 2017 Pro install last night?
