HSO (for Cubase) qustion - One Octave Up

I just purchased HSO key installer for Cubase 6. It is greate sound banks colection. I have a question about it. On the preset VIOLINS 1A comby I have 9 Key switches. One of them ( situated on A# 0 One Octave Up) don’t work. When I push this key (A#0) and I try to play I don’t have any sound. Wwen I push another key switces I have sound. What happend with One octave up? It not work corectly on Cubase 6 and Halion 4? I trayed also in HAlion Sonic but the result is the same. This key don’t work.
