I recently had a Premiere Pro project I’d been working on for a couple of weeks that refused to import some clips. When I attempted to link the media again, I’d get a box that said “the importer returned a generic error.” What’s especially annoying is that the failing clips were from the same camera as several successful clips; there seemed to be no reason for these three or four clips to simply not work and I could play them in a media player just fine. The failure didn’t even happen after an update because I’d been working in the project using the latest updated version.
I checked file permissions on the network server and everything was good.
I deleted all of the Adobe caches and manually killed all Adobe processes in Task Manager.
I restarted the computer and even tried opening an auto-save of the project, yet all of these failed to resolve the problem.
Adobe suggests that these generic errors on import can be caused by activation issues, so I signed out of my Creative Cloud account and signed back in. Didn’t work.
In the end, what I had to do was open Creative Cloud, uninstall Premiere Pro (keeping preferences), and reinstall Premiere Pro. No reboot needed! I still don’t know why this worked, but it did. Maybe my experience and solution will save you some valuable time troubleshooting this odd error.
