you may want to try forcing a reset. Here's how: Hold CNTRL + Shift and double click on the Sound Forge startup icon. It will ask 'Do you want to reset all Sound Forge Pro preferences to default values? You should check the box that says 'Delete all cached application data' and then click 'Yes'. Then try again to open the program.
