hey guys, I'm new to the forum. I just purchased Serato Sampling. after downloading it, the problem is that I can't install it. I use a mac by the way. so basically i'm stuck on a window that says "Choose plug-in format you want to install. After i did that, I entered my password and username like i'm supposed to do and still nothing happens. I live in Western Canada by the way. just finished a long nightshift at work.. I really want to get this working before i sleep.
