Digital Orchestrator Pro Set-Up On Win.

“Digital Orchestrator Pro” set-up on Windows 7. How can I make this possible? I’ve tried everything…changing compatibility settings, etc. Nothing works. I love this program and I have many musical files, which were/are the products of hours of labor, stored on an external, which now lay useless due to the incompatibility issue. Short of the obvious solution–having either a second PC or a second hard drive running XP–what can be done (if anything) to set this program up in Windows 7?
