acousticbrainz-gui.exe can't run more than one single time. I had to re-exctract it. Sometimes, the exe file even seems to delete himself. streaming_extractor_music.exe version in the zip file doesn't work either. Access denied. I've to extract it from essentia-extractor-v2.1_beta2-1-ge3940c0-win-i686.zip I tried so submit data by REST api, but I'had a 400. "message": "Key 'metadata : version : essentia_build_sha' was not found in submitted data."
