my older son started with Softmozart 6 years ago and have moved on to Acoustic piano since; now I bought the version 2.16 about 2 years ago for my younger son and it was working okay with the XP. I have since upgraded to Window 7, 64bits. I have an old Casio LK90 keyboard. I can't even pass the first installation step, the computer is asking for a digital signature of the HASP driver? what should I do?
