Main Demo will not import

Hi I am trying to import the main demo using the All option. Every time I get this error: Demo Import timed out and did not finish successfully. Would you like to retry the import? If this keeps happening, please contact support. I have already set php limits:
max_execution_time 120
max_input_vars 3000
memory_limit 128M
post_max_size 32M
upload_max_filesize 32M

and added the following to wp-config
define( ‘WP_MEMORY_LIMIT’, ‘128M’ );
set_time_limit(120);

Still is not working for me so I thought I’d just open a ticket. I am trying to import the main demo to Highend which is already installed along with all the required plugins. I also tried the other demos and those work normally. Not sure why the Main Demo (which is the one I want to use) isn’t importing. Please let me know next steps. I appreciate your urgency in this matter.
