Advanced Poll Problem - Poll ID does not exist.

This has probably been posted before, but I followed the two well written installation instructions posted by other users and I hit a problem. The poll shows up and all, but when I vote, I get the error message, "Poll ID does not exist."

In my polldata file, there's files named 1 and session.php. I do not have a file named 1.ip. One install post suggested there should be all 3 files.

Can someone please help?
Thank you
