Gisele, Suzanne, Natalie, Misha, Rae, Herbivore,
Did you ever get a reply? If not, I'll join your club ... dead silence from my post about the VEC Infinity pedal not working on my new Mac Mini.
I read somewhere that you must place your audio file in a particular directory (folder), I thought it was "documents", otherwise ES won't find it. But I tried playing a .wav file this morning, and it would not play even though I had it in "documents". But I have no trouble playing .mp3 files. If you want to convert .wav to .mp3, just download razorlame for free (google it); it's virus free, fast, simple, I've used it for many years.
