Try a program called Inkscape. It is free to download and has an absolutely amazing trace feature. Corel...eh...not so much.
Find the art you need traced and open it up in Inkscape. Click on the image to select it. At the top of the screen, click 'Path'. On the dropdown menu, click 'Trace Bitmap'. I typically use 'Multiple Scan'. I check 'Smooth, check 'Stack Scans' and uncheck 'Remove Background'. Then select the number of colors (including the background) and type it in the query for 'Scans'. Next I typically check the 'Colors' selection as most scans are in color to some degree. For greyscale images, select 'Grays'. Next click 'OK' and Inkscape will scan the image leaving a single path for every color. Next, I typically grab the vector layer and slide it off to the side, then remove the bitmap layer from underneath. Next, save it as an .eps file and you can import it into almost any if not all graphic programs as well as cutting programs.
