Have you manually checked with the Nvidia site that your driver is up to date? Auto systems failing so often.
And is this with (in project settings) Mercury Acceleration even when set to Software Only?
Is it on all projects, including those started in 2018, or just one?
Thanks for your response Neil!
Yes, latest video driver from Nvidia installed (just double checked now).
Mercury Playback is enabled for either hardware or software playback.
Neither setting makes any difference.
No projects opened in Premiere Pro 2018 play video files.
Doesn't matter whether it's an existing project, or an old 2017 project or even if I create a new project, still won't show moving video.
I just uninstalled and reinstalled Premiere Pro CC 2018.
Still got the problem.
Any other ideas?
That is normally a driver issue, and ... with going to "software only" in the Project settings for Mercury acceleration, you get your image back.
Last driver idea is occasionally it works to roll back a driver or two, so I'd try that.
Past that, going nuclear ... the Adobe CC Cleaner tool. Though the instructions say to uninstall the app via the CC Desktop app before running the Cleaner, from good personal experience, that works about 1 time in 4. It always works to get a clean install if you use the CC Cleaner tool to do both the uninstall and cleanup.
Then reboot your machine, and install a fresh copy of 2018. BEING CAREFUL to go to the 'advanced settings' option on the install dialog, and un-checking 'remove previous versions' ... you don't want it to do that.

Thank Neil Haugen!
I uninstalled the latest NVidia driver and did a clean reinstall of the previous driver.
Video image fixed and now visible in Premiere Pro CC 2018!
Hey, just like to help puzzle out how to get folks working again. Work's gotta get out.
