Satisfied customer, but ... – PianoGame PRO Review

The free version worked great. I bought the Pro version. I expected some extra features (I was hoping it would have more than one octave) and it was identical to the free version. Furthermore, it kept crashing after using for about 30 seconds. I try deleting and reloading several times, and the same problem happened. I wrote to tech support and did not receive any response. I am back using the free version.
