i know notigham says not to hydrate it, do it anyway in the future. 80 degrees seems a bit high to me! i am sure others know better, but i think you should try to get your temp down into the 70's before pitching. i am sure it is specific to each yeast just really getting into that though. tyler, jeff, randi or the Mikes could probably help better at this point.
like tyler i failed to get the lid on good once the beer still fermented and tasted great! after 4 days no bubles i checked it was working, and as soon as i sealed the lid, about 15 min and bubbles began.
for the record i would repitch!
