I don't see any errors from Navigraph. However, I do see that something has corrupted the checklist audio files. I suggest reinstalling the addon to resolve that issue.
Also:
Delete this file from X-Plane: .../Output/caches/CL650/chart.db/navigraph-tokens.cache;
Load a new flight with an airframe in career mode;
Make sure Navigraph is checked in User Settings > Networking;
Turn on aircraft power.
