Yeah if the next page loads you cant get back to that page, but you can use a proxy browser like http://www.online-browser.com to get to the page again. Just be sure to uncheck the "remove script" box.
Another option is with internet explorer when you reach the Reward Me page, before starting the clicking just hit CTRL + N on the keyboard a few times. It will open a clone of that same page in another window so you can try again if it didn't work at first.
Edit: supermagma Sorry I can't reply to your PM my post count must be 10 or greater to send PMs. PM me the info and i'll give it a try.
