I am a new Eris owner and I just plugged it into my Mac for the first time. I got a pop-up from Mac asking if I wanted to try a free trial for their mobile program but I declined. But I cannot find the Eris on my computer. It didn't pop up as an icon on my desktop. I want to upload some music to use the Eris as an mp3 player but I don't know how. Please help me!
