Premiere Pro 15.1 - ImporterQuickTime.prm - Freeze on Launch

Hello,

Since the update, i can't open Premiere Pro, it always stucks here. What should i do to make it work again? I tried to uninstall and install again through creative cloud, but still stucks at the same point.

Valantis,

Remove the Red Giant Unmult plug-in. I don't believe that version it is certified for 15.1.

Thanks,
Kevin

That's so sad and unacceptable. It should keep working with the previous plugins. Although i did everything you said, now stucks here: 

What should i do now?

Thanx for your time!

Valantis,

I would troubleshoot by removing all plug-ins first. Still getting the same warning? Let me know.

Thanks,
Kevin

It's probably not a good idea to expect plug-ins created for earlier versions to work at all or work properly and consistently after an update.  Happy to explain the logic behind this if you want.  You can revert to the previous version of premiere that worked and if you need features in the new update, you can have multiple versions on your system.    And you can reach out to RedGiant and see if they have a solution...
