Once the faulty file will be found, it should be fine (except this little part, everything seems to work fine).
(It's not one of the file I renamed which cause the crash as we haven't reinserted any of those files yet, so it's probably one of the file which have the same name as the english version but which might be a complete different sound file).

If it doesn't then... ¯\_(ツ)_/¯
