The other way to do it is to convert your image to paletted. You should be able to select a palette type that allows you to change the number of colors. The advantage of this is that it allows you to edit the final colors it uses. I didn't like the dull colors I got with corel trace, so using the palette conversion, I got a version like this:
This image will now Trace to give you the vector version as well, without changing the colors.
Suggestion: set dithering to 0 if you want to convert to vector.
Still single, can't imagine why.
