When I open a waveform (loop) to use in this thing I'm making, it works fine. But if I open multiple of them at the same time. (right click on the thing, open waveform, and then I select a bunch of them, not just one) They each are just loud crackly things. I don't know what I'm doing wrong. This is the 30 Day demo btw, but according to Adobe, its FULLY functional.
