Hello,
Problem? Do you mean problem with import of demo content?
Let us know what version you want to import and provide temporary wp-admin access, we will do the import on your site.
Create an account via Dashboard (Users > Add new) with administrator role http://prntscr.com/s3rc9m > provide us with username and password via the Private Content area http://prntscr.com/s5mao7 You can use any email for it.
Regards
