Weird advanced poll problem, pls help

Hi all ! Great script this is . I need to ask your help . I installed advanced quest book without no problems, works fine and great script btw .

But problems started with poll script , it installs ok and i double checked permissions, those are right . When i try to go admin section i get blank page

Apache errorlog complains

PHP Notice: Undefined index: login in /www/poll/include/class_template.php on line 88

And that line 88 is :

$this->pre_output[$filename] = ereg_replace("\"", "\\\"", $this->files[$filename]);

My server is linux with apache 2.0.44, php-4.2.3 and mysql mysql-3.23.51.

That vote script is too cool to miss so i prishiate if someone finds out my problem thank you .
