I installed Zen Cart with no issues. I've added mfgs, categories, products, etc... I was trying to follow the directions for customizing the "Sales Message Goes Here" and "Congratulations! You have successfully installed your Zen Cart™ E-Commerce Solution." Now I cannot log-in to my admin page. I get the following:

Warning: require(includes/languages/custom.php) [function.require]: failed to open stream: No such file or directory in /admin/includes/init_includes/init_languages.php on line 31

Warning: require(includes/languages/custom.php) [function.require]: failed to open stream: No such file or directory in /admin/includes/init_includes/init_languages.php on line 31

Fatal error: require() [function.require]: Failed opening required 'includes/languages/custom.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /admin/includes/init_includes/init_languages.php on line 31

I have checked line 31 on admin/includes/init_includes/init_languages.php and it is only "?>" I have not touched this file manually with any of the directions I've followed tonight.

Can anyone help please?!!?!?
