Wwise Recorder: Cannot Create Output File

Question

Hey!
 

I haven't been able to get the Wwise recorder to work successfully in Unreal 4.12.5 yet, and I'm unsure why.  In the output log, I receive the message "Recorder: Cannot create output file: 8650755".  The plugin is registered, and is set on an Ambisonics 3-3 bus. Has anyone else run into this?

 

Thanks,
Kevin
