Dimensionality doesn't matter. 2, 3, 14 will all work. What matters is that apparently vegan returns the results in some format other than a straight sites x ordination coordinates matrix, which is what dist expects. You'll need to convert it to one, possibly with as.matrix, or extract the coordinates component from a list, or whatever is appropriate for the output of that function from that package. The help file should tell you the correct approach for getting the nmds configuration itself.
