"Unit 0" is what hivelytracker uses to play sounds through AHI. If Unit 0 isn't working, hivelytracker won't work. When you go into AHI prefs, select unit 0 from the cycle gadget and click "Test Sound". If you get a sound, then AHI is correctly installed and at least configured well enough to get sound out of it, and so the problem is with hivelytracker.
If you don't get a sound, or you get an error, the problem is with your AHI installation.
BTW: 68030 is too slow to usefully use hivelytracker. A future version may include a 68k assembler optimised replayer which would help, but until then you really need an 060.
