How long did you wait before force quitting? If it was only a minute or two, try longer.
If that doesn't work, then remove all of the old queue items from the AME.
Then save your Pr project, and clean the media cache database from Edit | Preferences.
Reboot and try again.
If all of that fails, then trash your Pr and AME preferences and try again.
Not to come off sounding rude, but consider this a lesson learned. Don't update, or change anything in your system while you are in the middle of a project, especially a paying one. Finish it first, get it approved, master it, back it up, then go crazy with updates, hardware changes, etc...
Yeah the update process should be smooth and ideally have no bugs, but with the number of different configurations out there for both hardware and software, there's always bound for something to go wrong.
Adobe Media Encoder crashes on startup. Adobe updater downloads and runs the 4.2 update, but after getting info, AME still says 4.0.0. Is there a bug in the updater? I'm on a 2x2.8 Quad-Core mac osx version 10.5.8.
My projects are delayed as well. So very frustrated with all adobe's buggy software. I could find 10 bugs in 10 minutes for every app they make. It's just not worth the money period.
