I can download interactively the audio and play without incident. I just wish Alter Ego +3 was as interactive as +1 and +2. Also, as most of the questions in book are vague, there are not many answers to check. In activities book, you cannot input answers so to keep from flipping back and forth from questions to answers, you gotta save off answers somewhere else (like pdf on pc) to reference while attempting the questions on tablet. I guess this was an early design attempt or they were in a hurry just to get something out there.
