Stinger should work fine. What error message are you getting ?
Also, I just uploaded 1.3.5. Please start up MacDive and let it auto-update. Then head to Preferences -> Advanced, make sure your stinger is plugged in and in transfer mode, and click "SCAN".
You should get a list of potential serial ports in the combo box. Choose the one that looks correct - if you're not sure, send me an email with the list of what's in there and I'll let you know.
edit:
Not too many other updates in there. A couple of minor bug fixes, you can now exclude surface alarms, and the way you sort the main table is remembered.
