Advanced Poll 2.0.2 Multi Vote and warning

I have some problems with the Advanced Poll 2.0.2 (Text Version)

The installatin was no problem but after it they started...

1)After voting I get the following error:

Warning: Cannot add header information - headers already sent by
(output started at ...) in ..poll_cookie.php on line 22

I have already checked the position of the
<?php require "poll_cookie.php"; ?>
tag and it is on the first.

What else can I do?

2)I can just vote once. I know the opprtunity to delete the cookies, but thats's no solution for all the others who vote. In the admin I turned the ip-check of but it doesn't work.
What changes have I to do if I want to turn of the cookie-set?

Thanks for your Ideas!

Please mail me because I can't visit the forum as often I want.

1) It must be on the first line and you cannot include other script which sends headers etc. Note: You must also remove spaces and returns before the code

2) Remove the cokie code
<?php require "poll_cookie.php"; ?>
