Does not function with Sibelius 6

Unfortunately this app does not work with Sibelius 6.2 I contacted the company for an unimpressive back and forth email session which concluded with a diagnosis of "Num pad works, theres something wrong with Sibelius 6 so were not responsible."

If anyone is interested, my problem was that num pad was off by one button. For example if I wanted button 1 Id have to press 2 if I wanted 2 Id have to press 3. I connected using Tightvnc and Ultavnc. No difficulties connecting with either vnc, however both had the aforementioned problem. Hope this helps, thanks for reading.
