If the domain name has been booked by someone else, it won't be possible to get it back.

Thanks for the reply, yes i know that my original domain is gone for sure , I'm trying to get a new one when i go to Misc,Spend Credits,Domain Name the one i want seems to be available but i still get a error, i even went as far to go to godaddy website to make sure is available, I can get it there but i already bought the credits and i like buying the credits is less work for me lol. This is a ruff one for me i really don't want to lose that Domain name i filled up the form right i just don't know what it can be, i appreciate your time.
