Dry yeast only should be re-hydrated in warm tap water (probably boiled, then cooled). Many on here have just sprinkled to good results as well. Are you not seeing signs of fermentation? It can take a long time (3 days, in some cases) to get any signs. Also, don't look to the airlock. If it's bubbling, great. If not, it may not mean anything.
Look at the link I posted. If you scroll down it will give you all the directions on how to make a starter, but like I said, dry yeast doesn't need it. In the link, it explains that as well.
EDIT: I just re-read what you posted and realized what you did. Advice still stands, but it may not meld as a good response. Sorry.
