This code, forked from Till Kruess, should meet your needs as it did mine:
https://gist.github.com/andrewsfreeman/8062263
It hooks into the get_user_option for the admin color scheme – if a user has a WP 3.7 style saved, like fresh or classic, it forces a new default instead. Luckily, users can still change their own theme.
Satimis,
Change the line to
$credits = $wpdb->get_var($wpdb->prepare("SELECT tpyf_symbol FROM %s WHERE tpyf_category='credits';", $table_name));
And it should work properly.

Hello DLS & Diana,
I would believe that the issue is the console.log in the admin_footer function of DLS_Sign_Up_Sheet.
IE9 doesn’t support console.log unless you have their devtools open.
