Thanks everyone. Parker, owner of Laughing Dog Bikes in Amherst just said, "bring it in. I will contact Campy. Great guy. In the mean time, he said he would put on an alloy arm until mine is either replaced or repaired.

This all caught me buy surprise as I switch pedals at the end of the Fall and put on SPD for my winter shoes and then back again in the spring. The threaded insert never acted like it wanted to back out like this.
