Even if the Sphere Builders immediately started over after "Zero Hour" destroyed the Expanse, there's no way they'd have enough time to cover a quarter of the galaxy in only 400 years. And like I said, they wouldn't consider it worth the effort, either. Now that it's common knowledge how to destroy the Spheres themselves.
Given that they possess time travel and time communications, how does "having enough time" enter into it?
Pick a different part of the galaxy a few thousand light years away and centuries in the past (about when they started last time) and begin again.
Archer can't provide the people in that section of the galaxy with the solution, because it hasn't been found yet, and won't for centuries.
