We're really sorry for the confusion and completely understand how frustrating it must be not being able to open the projects. We appreciate your feedback and will make sure to clearly specify on our website that Ableton version 12.1.5 or higher is required to prevent this issue in the future.
We’d love to find the best solution for you. Please reach out to us directly so we can assist you, whether that’s with a refund or an alternative option that works for you. Your feedback helps us improve, and we truly appreciate your patience.
Looking forward to resolving this for you as soon as possible. Thanks again!
Best regards,
Team Tech House Market
