Can't access my website with new domain

[dalip_malpani]

I received a ticket for choosing a new domain in place of "x10hosting.com", but i couldn't choose in time. So, I was assigned the domain "x10host.com" by default. But now I can't access my website through this new domain. My website is: mmpindia.x10host.com (previously mmpindia.x10hosting.com).
