Page not found error on subdomain

I am using godaddy for domain registrar and hostgator for web hosting for my current website. I went to cPanel of hostgator and created a new subdomain livewallpapers.javaexpericenc.com (document root was set to public_html/livewallpapers)

Then I went to Quick install and installed wordpress on the sub domain. For Application URL, in the first drop down I choose my sub domain and left the second text box as empty.

I get a congratulations message and link to my wordpress admin as:
http://livewallpapers.javaexperience.com/wp-admin

But when I visit above link I see 404 Page not found error.Could it be name server issue on godaddy side.

Pls help how to debug this problem.
