banner link not working in affiliatesshortcodes

In affiliatesshortcodes.php, there is this line for looking at available banners:

If you would rather use a banner or button then we have a wide selection of sizes <a href="%s">here</a>.', "profile.php?page=affiliatebanners" ), 'affiliate')

Which generates the url link .../affiliates/profile.php?page=affiliatebanners

But that link is 'Not Found'

We have Affiliate System Administration - Banner Settings - Enable Banners set to yes and have entered a Banner Image URL.
Under Affiliate Banners we can see that url and the banner image.

So why is the link 'Not Found' ?
