Database does not exist (missing info.cfg)

I have a number of database files, originally created from csv files. All are fine except one, which displays the message “Database does not exist (missing info.cfg)” whenever it opens. Other than that it works fine and data can be accessed by functions in other databases. How can I correct this issue so that the message stops?

I did some research, and this error message is part of the server code for the upcoming Panorama X Server project. The current version of Panorama X includes quite a bit of code for this project, but none of this code should ever be running on your computer. Could you send me a zipped copy of this database? I would like to investigate this as there should be no way this message can appear on your system.
