The Irish Potato Famine, also known as the Great Hunger, began in 1845 when a fungus-like organism called Phytophthora infestans (or P. infestans) spread rapidly throughout Ireland. The infestation ruined up to one-half of the potato crop that year, and about three-quarters of the crop over the next seven years. Because the tenant farmers of Ireland—then ruled as a colony of Great Britain—relied heavily on the potato as a source of food, the infestation had a catastrophic impact on Ireland and its population. Before it ended in 1852, the Potato Famine resulted in the death of roughly one million Irish from starvation and related causes, with at least another million forced to leave their homeland as refugees.

You could no longer do standard seaming, but you could do free motion embroidery.
If you want to fix this there are a few common ways that they get broken and fixed from home:
thread could be jammed, just remove the needle plate and clean
hasn't been lubricated in a while, either take it in and have it done or do it yourself with a drop of sewing machine oil
or because they're dropped, in this case just look for a switch.
if it's not any of these, you may want to take it in and have it looked at :-)
