Hi
Sorry for the delay!
Is it always stay in loading screen without any error information?
Because there are many pictures needed to download to your server, so the process is a little slow.
Also, we include the demo data in the “All File zip package”, if you download the All File package on Themeforest, you can find the demo data in the folder.
By the way, if you don’t mind send me your WP Login details via the private reply, I will help you import the demo data.
Thanks
