Add 1/8tsp of bakers yeast since I didn't have real brewer's yeast culture.
It wasn't, by chance, quick-rise yeast? Sometimes the more robo-yeasts can screw up the process. Maybe try the actual brewer's yeast next time?

I know if you swing by the LBS (in this case, Local Brewers' Supply), they will probably have the exact yeast that you need. You can also get them in smaller portions, like the bread yeast at the grocery store, rather than the big jar of $$ brewers yeast.
