I'm assuming you now have the full paid version. So how do you open AD for a project in GTP4? For example, do you click on the + symbol to add a track? Then which one do you choose: Audio Track, MIDI Track, or Instrument Track? Under Instrument Track, I get Studio Instruments, then SI-Bass, SI-Drums, SI-Piano, and SI-Strings. If I know exactly how you are opening AD in a new track, that might help. Thanks.
