mrnutsandbolts... EraStar use to be Constellation and before that they was RedWood and before that GREEN RESURRECTION LLC
They changed names again, i dont know why if that is what your asking i dont think they go under so they can start over again i think they just like changing the name of the Company.
Maybe they dont ripp everyone off and change the name of the company like i have read on the web i think a change is cool.
