What recourse do Royalty Owner have when Operating Co, Files for Bankruptcy?

Atlas operating Co LLC has filed for Bankruptcy and we as royalty owners were not notified. The co has an answering machine and I leave a message but never get a call back. I have written letters, sent e-mail and phoned. I found out that the bankruptcy was filed in NY court 7/27/16.

The last time that I rec'd. anything from the co were Div orders on Sept. 2, 2016.

Any advice on what recourse we can do.
