Okay, this ought to be pretty straight-forward, but we have a bit of a glitch in the file itself --- start by opening it in Inkscape and doing
View | Display Mode | Outline
which will result in something like:

Note that the top left star is darker than the others --- it's a duplicate and should be removed, since stacked geometry can confuse Carbide Create.

Selecting the graphics in Inkscape reveals that there are 50 objects, of types "Star, Clone" --- doing:
Path | Object to Path
converts the star which was importing fine into a path, but leaves the other 49 as clones of it. Not seeing any easy or obvious way to change that, and it still only imports one star.... Saving it as a PDF and re-opening that in Inkscape results in a group which when ungrouped is 50 paths. Importing that SVG results in:
