How do I UN Rar and Also how can I possibly get dj2.0 to work with my cdr drive

To unrar use WinRAR. Get it here: http://www.rarsoft.com

If you are having problems with DiskJuggler you should try converting the cdi-file with the cdi2nero-utility and then burn it with Nero. It works for me every time.

Get cdi2nero (0.9 beta 2 TAO) here: http://www.dccopyworld.com
Get Nero here: http://www.ahead.de
