Install issues with Index.php

General Installation & Upgrade
1

I installed the latest version of CS-Cart and ran the install at /install.



Now, when I try to access the site, it shows:



Fatal error[color=#000000][font=Times][size=1]: Class 'Registry' not found in [/size][/font][/color]/home/users/public_html/index.php[color=#000000][font=Times][size=1] on line [/size][/font][/color]20



When I access index.php, this is line 20:





define('INDEX_SCRIPT', Registry::get('config.customer_index'));




Not sure what config.customer_index refers too. All the files seem to be in the folder. Should I be looking for a particular file?



Thanks.
