If you changed your domain within the last couple of hours, the server probably has not updated the vHosts file that tells the server how to handle requests for your domain. Give it some more time to start working.
sory to disturb again. I want to start fresh, ie, delete this account that i have and back to my old domain (www.bruno.x10.mx), it is possible?
( If you delet my current account i have to sign up to x10hosting again? or not?)
