Ok, thanks, that worked! Erasing my browsing history was easy. But finding my "cookies" was another story!! And then I had to know exactly which website it was on the list!! For those of you who are technologically challenged like me, here's how I did it on my MAC:
Go to Safari
Click Preferences
Under Cookies, click Details
Go down the list until you find polldaddy.com, then hit delete

After doing this, I was able to complete the survey. But as others have said, it's not that accurate. Fashion Cafe is listed as well, and it is out of business too.
