I made a started last night. Since we had the AC on, I put it in the oven with the light on. It was bubbling away when I went to bed. DH, no knowing what I was doing (Do they ever pay attention?) turned off the light when he went to bed.
It stays pretty cold in our kitchen at night.

This morning, I turned the light back on, but its not bubbling anymore.

Can it be saved? Or am I on to round three?

You have to FEED your starter. Some do it every 12 hours and some 24.
