Job manager + atahualpa = not working

Hi there,
I've recently installed the job manager(http://pento.net/projects/wordpress-job-manager-plugin/)
plugin into my webpage (using atahualpa theme).

Whenever I try to access the job page, that's the error I get:

Warning: include(/home7/myinfose/public_html/sandbox/wp-content/themes/atahualpa/page.php) [function.include]: failed to open stream: No such file or directory in /home7/myinfose/public_html/sandbox/wp-content/plugins/job-manager/jobman-display.php on line 197

Warning: include() [function.include]: Failed opening '/home7/myinfose/public_html/sandbox/wp-content/themes/atahualpa/page.php' for inclusion (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home7/myinfose/public_html/sandbox/wp-content/plugins/job-manager/jobman-display.php on line 197

Can someone help me, please?

Thank you!
