Music trainer slowdowner

This program has stopped working in the last 2 weeks. It has not enabled me to laid songs as it did in the past and there is always an error message .i have sent numerous reports to the developer and have had no response where the turnaround has been usually 3 days. I do nit know why they have chosen to drop support on what had been a good product.
Be careful with this product now.
