My KingSize Theme is not working

Hello, I need some help,
I just got my KingSize Theme Version 5.1.8 and I have tried 2 things and none of them work.
First, I just tried to modify the background picture that come with the Theme, and when I launch my site, the new image shows up like for half of a second and them goes back the the default image.
The second thing that I tried with no success was Importing and Installing the Demo, I always get error “405 not allowed”.

Any help?
