I just wanted to add to the searchable knowledge-base here by mentioning that when installing the software for this card on a fresh install of 3.1.4 be sure to use "expert" mode and do not allow the install script to replace any of your newer libraries with older ones. I usually use "intermediate" install scripts and using that the software will overwrite several libraries and devices like the fast file system. Once overwritten I started getting immediate crashes when clicking on CD0: device in dopus. Went back in time and redid the install on expert and saved all the new files from 3.1.4 and the studio 16 software, the AD516 card, and os 3.1.4 are all fine.
