I'm here to help you restore connection, @rarceneaux.
First, I suggest to restart the Database Server Manager, then move the file to a different folder, and set Power saving option to never. Take a look at this article for detailed steps on correcting the connection issue Error message: Connection Has Been Lost.
Go ahead and reply to this post if you run into any other issues, and I'll be here to help. Thanks for reaching out! Have a great weekend.
