the scores you submitted were not officially registered and have been deleted. You should use the links on the work page marked as “Add Multiple Files” (underneath Scores) to re-submit the scores properly.
Also, the MP3 files for this cantata – or, at least, the one which you did upload correctly – do not appear to be an orchestral performance. Is it even the right piece?
You may wish to visit this page and upload a new version of that file for the fourth movement. The MP3s for the first three movements weren’t submitted correctly and must be uploaded using the “Add Multiple Files” link under the Performances heading.
