Dummy Data Import Error

Hi Guys

I have installed Enfold theme ok and everything seems to be working fine but when I choose the the dummy data import button I get the following error:

Importing didnt work!
You might want to try reloading the page and then try again
(The script returned the following message:
Fatal error: Allowed memory size of 41943040 bytes exhausted (tried to allocate 84 bytes) in /home/zimoci5/public_html/webdev/wp-content/themes/enfold/framework/php/wordpress-importer/parsers.php on line 144)

Any help to fix this would be great.

Thanks
J
