Premiere Pro 2019 CC and I'm still stuck with the red ribbon in Windows 10 1809 which auto-installed an update earlier today. Brand new project created in PP 2019 CC involving only two layers from a single Photoshop PSD. Installed the latest drivers for twin GTX 1080s in SLI, 64gb memory, Ryzen Threadripper 1950x,16 cores, 3.40gHz, preferences set for Mercury Playback Engine GPU Acceleration (CUDA). Trying to apply Effects/Color Correction/Change Color. Sigh!
