Cubase SE and Hypersonic

[kats]

Is anyone familiar with these two programmes? Ive just gotten them to do some recording and am having a horrendous time trying to get them to work! I cannot find Hypersonic in the VST instruments in the Cubase programme, there is no sound when I play my keyboard (which is connect to a m-audio pro fasttrack box via MIDI).... any help would be very much appreciated thanks!
