iPod/iPhone app weirdness

Hi, folks,

Has anybody had problems with the iPod / iPhone app? I've just started using it, and it seems great; but it seems as if I'm getting the wrong audio tracks paired with the wrong menu items; so when I click on (for example) "Giving Instructions to the Ayi", I get the audio from "It's Not the Heat, It's the Humidity." It's sort of ChinesePod roulette, which is fun in its own way; but if anybody has any idea how to fix it, it would probably be useful.

Best wishes,

Will
