Score audio issues not updating :(

I finished my score and all, but the audio on the Musescore website won't reflect the changes and new additions I just made to the score. The notation and all is updated just fine, it's just the audio having issues. It sounds just fine when I'm in the Musescore program but the audio seems to be having issues uploading. Whenever I try to also update the pre-existing score within the Musescore program, I'm faced with an error. Even with replacing the actual file itself though I get issues. I don't want to reupload a completely new score and am wondering if I can do anything about this. I've had this problem for a while now. I even tried to update the website on project properties that my score is listed with and nothing worked :/ Please send help
