Hi,
First, which version of CorelDRAW are you using?
If you have everything installed properly, you should be able to access Cutting Master 2 from your Application Launcher in CorelDRAW. That button looks a little different in different versions of Corel, but in 12 and X3 it looks like a little rocket ship at the top of your screen.
From there you can add registration marks if you're planning on contour cutting inkjet transfers.
Or, if you're going straight to vinyl, you can also access the Cut/Plot dialog.
If you'd like to know the specifics of contour cutting, I'd suggest opening Cutting Master 2 from your Start Button and opening the help file. It will open a PDF with just about everythign that I could post here.
If you still have problems from there I'd be happy to answer them.
Lastly, have you gotten to the cutting dialog yet? Have you tried cutting something yet? If you have and there was an error on your plotter's display panel, there may be a simple setting that you'll need to change.
