Advanced Poll - How can I vote more times ?

(Sorry for my english)
----
I installed advanced poll (installation is OK). The problem is that I can't vote anymore!
I created a poll and i voted one time, then I deleted the poll and created another one (always with the first ID). I can't vote because it says me that I already voted!! I check all the options but I don't know where is the trick!! (I created the second poll 2 days after the first).

Thanks for all responses!!

delete all your cookies first.

No IP-Logging !

I am in the middle of conducting a poll and I want my voters to vote again after 12 hours. My voters can't vote again. I tried turning off IP checking, but that doesn't work. I don't want to ask my visitors to delete thier cookies. For the users that want to vote over again, how can I get them to vote without deleting their cookies. Turning off IP checking does not work.

Is there a way for me to expire there cookies and allow them to vote again

Thanks anyone for your help

global $HTTP_GET_VARS, $HTTP_POST_VARS;
$cookie_expire = 169; // hours

poll_cookie.php , set it to 11 hours and there you go
