Proxima Centauri's flare: effects on a terraformed planet

Imagine that, in a thousand years, the star system of Proxima centauri has a planet located in its goldilocks zone that has been terraformed by earthling settlers.

We do not really know what the biosphere of such a planet will be like, so let's assume that it is equal in size, sea/continent ratio, atmosphere, and animal and plant species to the Earth in the 20th century, including the most exotic microorganisms. The only difference would be that it wouldn't have plate tectonics.

Let us suppose that one million human beings live on this planet, in a society that has voluntarily renounced high technology and lives like its ancestors of the year 2020 in a simple, common existence, with satellites and computers, but no nanotech nor AIs. Let's supose they dominate nuclear fusion power.

Would the human species survive? Would any life in Proxima survive?
