I've been using Resolve 15 for a few months. Really like it and plan on upgrading to the paid version soon. I saw a video of the new features and decided to download and upgrade to 16. Now all of my video clips and thumbnails appear as solid black. Audio is there and clips seem to be the right length, but can't see anything. Just to check, I rendered a short clip to see how it would output. It outputs a solid green "blob" of a screen. Am I missing something on a setting or something?
