Okay, I thought the spokes had just seized up on you, based on your initial post. If the spokes were bottoming out, go and get yourself 16 or 18 spokes of 288mm, double-butted if you can (although keep in mind that butted spokes will stretch more, so maybe you'd want to go with 287mm to make sure they don't bottom out), and again be sure to build the wheel back up with spokes sitting in the same spot as before on the hub flange.
