Premiere Pro: Loading Footage for Project Problem When I open my project it loads the footage in the background. Unfortunately, it stops at a certain point (close to ready) but I can't figure out which file is causing the problem since my folder paths are too long (I am only seeing something like: G:\Video\Projectx\scene1(footage)...). When I open the project it shows me this error message: Video Filter missing: AE.ADBE Aud Stereo Mixer. Since I have imported different other projects, I cannot figure out which file is causing this error as well.

I import:


a lot of .MOV files
6 AE projects
some png and jpeg


What I tried so far:


deleting the cache
changes cache's location
other projects work fine
restart PC


Any ideas how I can debug/solve the problem?
I would try following this YouTube tutorial. What they do in it is make a new premiere pro project and then import the project into it.


                
            

Summary of video:


Open premiere pro and make a new project. 
Go to the media browser
Navigate to where your project is saved
Right click on it and press import
Check import entire project and tick Create folder for imported items and click ok
Go to the tab where it says project:[project name]
Expand the folder there
Find the file  which has a icon which looks like lots of tracks on a timeline
Drag that into the timeline
Save the new project
