Having an issue with Muse Sounds in regards to uploading to MuseScore...

Hey all

To preface, I'm fully aware of how the uploading process should be done to get the desired effect of having muse sounds playback in scores uploaded to Musescore.com.

But, with one score in particular, I'm having a very tough time with getting it to upload properly...

It uploaded 1 time with musesounds, but then it would refuse to update the audio upon subsequent changes to the score. I am uploading it privately, my preference setting is set to "always" for updating the audio when publishing a private score, My playback setup is set to Muse Sounds library, and I'm using the "Publish to Musescore" selection in the Publish tab of the studio software. It then prompts the "Exporting Audio" Dialogue with the % bar, which takes forever given how long it is, then will open the browser to update or upload as normal, then after processing, it has MSBasic playback... kind of annoying and making me scratch my head a bit...

For further detail on the piece, It's 2 movements long, at a duration time of about 12:30 minutes. I'm not sure if the length of the piece factors in to this issue or not...

I've also tried to save the score as a copy, delete the online score, and post it as a new score, to no avail in getting the desired effect... What's going on here?
