With this explosion, there was a ~$200 million satellite destroyed as part of a ~$60 million launch. We'll probably see much cheaper payloads to go along with cheaper launches eventually, but for right now the payload loss dominates, so you have to look at that as well.
For this particular problem, the risk to the payload will be eliminated by not attaching it for the static fire. Any risk during the actual launch would still affect the payload, though.
