Demo import didn’t worked

when trying to install the demo using Blocksy companion, it gives an error
:
The connection to our demo.creativethemes.com server didn't worked. This connection is required for importing the starter sites from our demo content server. All you have to do is to contact your hosting provider and ask them to white list our demo server address.

tried to resolve this issue with the technical support of my hosting provider, they cannot do anything.

is there another way to set the start page? import xml maybe?or via ftp?
