easy populate problem

Hey all...I got this bunch of code when I tried to Upload a EP file to the Datebase using easy populate 1.2.5.4:

Warning: move_uploaded_file(/var/www/vhosts/partyjubilee.com/httpdocs/catalog/temp/Full-EP2006Dec13-13012.txt) [function.move-uploaded-file]: failed to open stream: Permission denied in /var/www/vhosts/partyjubilee.com/httpdocs/catalog/admin/includes/functions/extra_functions/easypopulate_functions.php on line 57

Any help would be great... Thanks
