Your song title is Untitled Song and that is generally what the BiaB initial song title is when you first open BiaB and only a C chord is shown: note that it is not a saved song. In the VSTi did you click on file, selected your song, then clicked on generate? That is the method I use and I have no problems using the BiaB VSTi in the current Studio One Pro 5.

If you have done the above a more detailed description of your method might help.
