Hi guys,
I created a project and tried several times to cook it, no problem.
Then I imported some .WAV files, created Sound Cues and played them from Blueprints.
After that I tried to cook the project and the cooking failed.
Now it doesn’t cook anymore, also after deleting all Cue references and audio files. 
The logs are attached and I hope you can help me.
(I’m using the ready compiled editor)
