@Colleen - did you try the WordPress.org support forums? http://wordpress.org/support/forum/how-to-and-troubleshooting? Also for best results, make sure to provide useful information about your setup (i.e. which theme and plugins are installed) and any troubleshooting steps you've tried previously (disabling custom themes, disabling all plugins, viewing your browser's console log to see any error messages, etc.).
