I had a look at this, and updated the Site Domain settings in your website config.
You had some unusual capitalisations in the domain name in the settings - I don't know for sure if this made any difference, but when I changed them to be all lower case, and waited a couple of minutes for caches to timeout etc, it then all seemed to start working fine!
So - maybe it was this - or maybe it was something at the Godaddy end - perhaps if the domain expired for a while the DNS wasn't working correctly until the renewal went through.
