Welcome to the forums ;D
Even though you followed the recipe to the letter, you did use a different yeast than the one specified.
As David asked, was it a few days or a few hours?
If it was a few hours, most probably the yeasties pooped out :-\ in which case I would repitch using Fleishman's yeast from the market. Keep in mind that using Fleishman''s will yield a sweet mead where as using Red Star baking yeast will yield a dry mead.
If it was a few days, I would mive the jug in a warm place (around 80 deg F) for a while and see if that gets them going again. Since baking yeasts prefer a warm environment, moving the fermentation vessel closer to warmtm should help.
Hope that helps,
