I have loged in your administration. Are you sure you installed joomla form hot_start? It looks to me like you copied there standard joomla, there is not evidence that that is hot_start ????
I repeat , in zip you got from us there is hot_vortex16_hotstart.zip, in that zip file there is folder hot_vortex16_hotstart , you should copy everything from that folder to your hosting web root folder.
