cant install demo data

Hello,

The template looks great but I cant get the demo data of the version I want to install.
The default demo installs fine but when I try to install the startup-demo i get an error saying im porting didnt work. you might want to reload the page.

Its a fresh install of the latest wordpress and enfold.
I am using the uk company 1and1 to do the hosting. I tried to upload the demo manually using the xml but also didnt work.

I have also edited the default-constants.php

function wp_initial_constants() {
	global $blog_id;

	// set memory limits
	if ( !defined('WP_MEMORY_LIMIT') ) {
		if( is_multisite() ) {
			define('WP_MEMORY_LIMIT', '128M');
		} else {
			define('WP_MEMORY_LIMIT', '128M');
		}
	}

	if ( ! defined( 'WP_MAX_MEMORY_LIMIT' ) ) {
		define( 'WP_MAX_MEMORY_LIMIT', '256M' );
	}

Any thoughts?

Thanks in advance
