Error when logging into dashboard: Failed to open stream

I changed a small amount of code in my admin.php file and then got this error when logging into my dashboard:

Warning: require_once(/home/tylerl/public_html/b-linda/wp-content/plugins/wp-e-commerce/woo-integration/woo_integration.php) [function.require-once]: failed to open stream: No such file or directory in /home/tylerl/public_html/b-linda/wp-content/plugins/wp-e-commerce/wpsc-admin/admin.php on line 30

Fatal error: require_once() [function.require]: Failed opening required ‘/home/tylerl/public_html/b-linda/wp-content/plugins/wp-e-commerce/woo-integration/woo_integration.php’ (include_path=’.:/usr/lib/php:/usr/local/lib/php’) in /home/tylerl/public_html/b-linda/wp-content/plugins/wp-e-commerce/wpsc-admin/admin.php on line 30

I didn’t even change line 30. So I changed it back to its original and reuploaded admin.php and still get this error when going to the dashboard.

Has anyone had a similar problem? Is there something I should do to flush the site?

Thank you
