Okay now we have to wait 24 hours for the dns changes to propagate. I renamed your .htaccess file to copyhtaccess, please don't rename it until we get your site back up.
Ok try now. Brute Force was blocking you. After you login, delete anything that has to do with this domain (hameroha.com). Go to the sub-domains and Advanced dns editor and delete anything to do with that domain. Then post back and I'll complete the domain name change.
That's where your problem started. You changed your domain to a domain (hameroha.com) you were already using as an addon domain. The domain name didn't complete because of the conflict. Can you login using this url: http://stevie.heliohost.org:2082/frontend/x3/index.phpcp
What happens when you go here and try to login? http://coplaypl.heliohost.org/cpanel Make sure to use all lowercase on your username. Edit: Ok it should work now. I just checked and Brute Force was blocking you.
@Krydos - His account doesn't seem to be parsing php. Just serves a blank page. I created a test php file and it does the same thing: http://hameroha.com/admin_test.php
Give it 24 hours.
The reason I wanted to recreate your account is because it used to be on Johnny and you deleted it. Sometimes not all the records get completely deleted.
Ok. Also make sure your ONLY using the name server option at godaddy. Remove the A record again. Ok I'm fixing to delete your account and recreate it. Ok I've recreated your account and I'll PM you the password.
