Glad to hear you got it fixed (or that it fixed itself). Its pretty scary when your site goes down like that and you have no idea why.
In the first instance Hostgator may be able to offer assistance - or at least advise if the server is down etc.
In most cases where you cant sign in to WP or youre getting the white screen of death, its due to corrupt or missing WP admin files. You can try deleting the wp-admin and wp-includes folders and uploading new ones downloaded from the wordpress.org site.
If all else fails and you have a current backup (of both your data, your plugins and your theme if you modified it) then it might be quickest to delete all your website files and run the WP install again from the Hostgator cPanel. Then upload your backup.
