I was reading this thread as I started my LE 2013 cab/shiraz kit, and had the same problems. I started at 1.080, but pitched the yeast anyways. On day 2, the SG read 1.080 again, but there was some fermentation starting, so i'm surprised it was not lower. I vigorously stirred the must and squeezed the skin pack several times, and was able to a achieve a reading of 1.09 before I closed it back up.
Follow the directions, and keep squeezing/stirring. The grape skins will continue release sugar as fermentation continues.
