Hi
I got the following from Auctiva and it worked!
in order to clear your cache in your Internet Explorer 7.0 web browser, please select "Internet Options" from the "Tools" menu. Then, under the "General" tab, click the "Delete" button. Click the "Delete Cookies" and "Delete Files" buttons on the ensuing page, followed by "Close" then "OK". Once this process has been completed, close and re-open your Internet Explorer 7.0 web browser for the changes to take effect. Also, please ensure that only one browser window is open when you are doing this or your cache may not empty properly.
Hope it works for you
