About the bread maker hot cross buns

Hot cross buns not rising - I followed the bread machine recipe to the letter, but my hot cross buns aren't rising. The yeast is fine - a loaf of bread I made with it is perfect - but after 30 minutes, there was no rise at all, and 30 minutes does seem a little short, so I waited longer. After an hour, still no noticeable rise. It's been two hours now, and still nothing. I've heard that sugar and fruit retards yeast, so are you sure the ratios in this recipe are correct? I think the amount of sugar and fruit has simply killed the yeast.
