Did you even look in the box the AR came in? Yes, there's PC Software. And yes, it's a lot faster that way obviously because you can copy-and-paste..yes, there's a reason for the USB cable that came with it..
If you lost the CD but still have the cable, you can download it here:

If you don't have the cable, then you need to get a new one :]
