I haven't tried to culture yeast from a commercial bottle of beer (yet),
but I have used vials of dormant yeast. Starters made from the latter
usually take a couple days to get going. The yeast in a bottle of Sierra
Nevada Pale Ale is probably also dormant, and so probably takes a couple
days to start working. My guess is that your general procedure is fine, but
that 45 minutes isn't nearly enough time. Next time you should give it a
couple days.

As for your current predicament, here's my advice: Considering that you now
have a container of wort that is just waiting for bacteria to attack, I'd
add some dry yeast ASAP (proof the yeast first to make sure that it's
good!). You don't want to wait and see if the Sierra Nevada yeast is going
to start (and you have no way of knowing if what *does* eventually start is
the yeast that you added, or something else).
