We sent you an email with restore options about 6 hrs ago.
Do you have more information about the internal error you mentioned? Did the error occur when trying to log into HostGator or CodeGuard?
Normally, if you would like to perform the restores yourself, you can access your CodeGuard account after you log into your HostGator Optimized WordPress dashboard. Here is how: https://support.hostgator.com/articles/optimized-wordpress#manage
