Error message please help!

I updated a plugin from my admin dashboard and now receive this error when trying to bring up my page or trying to get to my admin page:

Parse error: syntax error, unexpected ‘=’, expecting ‘)’ in /home/content/d/a/n/danceladie/html/wp-content/plugins/wp-e-commerce/wpsc-includes/category.functions.php on line 238

How do I fix this problem if I cant even get to the dashboard to disable or delete the plugin?
