I keep getting this message whenever I try and log into the admin area

Warning: main(includes/configure.php): failed to open stream: No such file or directory in /home/sinister/public_html/catalog/admin/zen-cart/admin/includes/application_top.php on line 74

Warning: main(includes/configure.php): failed to open stream: No such file or directory in /home/sinister/public_html/catalog/admin/zen-cart/admin/includes/application_top.php on line 74

Fatal error: main(): Failed opening required 'includes/configure.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/sinister/public_html/catalog/admin/zen-cart/admin/includes/application_top.php on line 74

I did change a file name but it got changed back right away, also in the faq it says that in order for a store to become live you have to submit it, but I can't seem to find the folder for that anywhere is it still nessecary?
