Accessing cpanel on copied account before domain name propagation

I've recently transferred an account from another host using WHM copy. I want to check this account out through cpanel to make sure everything is ok, but can figure out how to get in. I've tried http://ipaddress/cpanel and http://ipaddress:2082/cpanel to no avail. Any ideas?

 

Tried http://ipaddress/cpanel/ and still no workie. Comes back with a page not found. This is not good as I cannot really check out the account before I start the domain name propagation.

 

I found the problem. It was because the imported account used a control panel theme that I didn't have. Once I set the custom theme to no, it worked.
