It sounds to me as if it is a cookie problem, but it should be easy to solve.
In Internet Explorer, go to Tools>Internet Options.
Click the Delete or Delete Cookies button to delete your Cookies and also your Temporary Internet Files.
Go to the Security tab. Ensure the slider is set to Medium (not Medium-High or Custom).
Go to the Privacy tab. Ensure the slider is also set to Medium (not Medium-High or Custom).
Under the slider in Privacy is a button marked "Sites". Click on this and add www.advfn.com to the allowed list.
Click OK and OK and close ALL of the internet browsers you have open.
In Firefox select the Privacy tab and hit Clear Now (cache, cookies, and history).
Then go to the Content tab and click on the “Exceptions” button to the right of Block Pop-up Windows. Then type in advfn.com and click the allow button. Then click the close button.
Log out of the site. Close and re-open your internet browser and then try logging on iHub again. If you still have problems please let me know.
Thanks,
