Hi Clinton, sorry for the delay, we don’t work 24hs a day. We are not from Spain, but i have family living in Arinaga, same island you are.
I don’t know why you say that, but the demo is working fine. I can’t see the errors you said.
Let’s do the following, do a fresh install (manually) of Magento in your server, don’t install nothing more, send to support (at) hellothemes (dot) com your ftp, and admin details so we can set up hellocurl.
