I have just purchased, downloaded, installed and registered my copy of the Professional Authorized Steinway but have not been able to hear it at all. I tried to use it in DP 6 and it produced a spinning pizza wheel and a report that Digital Performer was not responding (crash).
So then I tried using it with Finale 2009. Same thing. FInale quit abruptly.
I am wondering if I have encountered a known issue, or if I have made a mistake along the way....
