This App does not work after installing OS9

No longer works after installing OS9
As expensive as this app is, you would think the developer would be acutely aware of these issues with OS9.

Im sure there are people who use this on a day to day basis. Not being able to access any of my work is inexcusable on the developers part.

Apple should consider allowing users to revert back to the previous version for instances just like this.
