smilies module doesn't work

I installed the module (smileys-4.7.x-1.x-dev) and tried to set smilies as it goes in install.txt:

4. Now you can either:
(a) Add the included example smileys to your SQL tables by using:
mysql -u username -ppassword drupal < examples.mysql

(b) Go to the "smileys" page in "administer > filters" and
add your own smileys. There are two blank smiley pictures included in
the examples directory to get you started.

unfortunately, all I am getting is:

Fatal error: Call to undefined function: drupal_render() in /home/lugovsa/public_html/community/drupal-4.7.5/modules/smileys/smileys.module on line 254

Can anyone help, please?
