I am having some major issues with the Nictitate theme

Hi,
I am having some major issues with the Nictitate theme and I am receiving no response from them. I need to update and I am not able to download the new file from my account. Also, my site is not finding my home page. I have no idea what is happening. I am working in a child theme, but up until now my home page has been fine.
Please help,
Thank You
