Advanced Poll in Windows NT problem!

Hello,

I've installed de text-file of AP 2.0 on a Windows Nt server.
But It doesn't work ok.
When I log in at poll/admin/ everything is ok .
But then I see things like :
Warning: flock(): supplied argument is not a valid File-Handle resource in d:\www\blabla.nl\www\poll\include\class_session.php on line 50
and :
Warning: Cannot add header information - headers already sent by (output started at d:\www\blabla.nl\www\poll\include\class_session.php:47) in d:\www\blabla.nl\www\poll\admin\common.inc.php on line 16
Under it, there is just the normal menu to create new polls etc.
But when I click on it, i've to log in again.....
Please help !
Thanks !

if you copied and pasted the code needed to show the poll from the admin section

To emded a poll into a webpage insert the code snippet from below:

you will get two php include lines... the first one (poll_cookie.php) needs to go at the front.. that is the beginning of all the code on that page...
