Website Payment Standard - post payment processing

[cafediem]

I have a simple form like this:

<form action="https://www.paypal.com/cgi-bin/webscr" method="post">
    <input type="hidden" name="cmd" value="_xclick-subscriptions"/> 
    <input type="hidden" name="business" value="myemail"/> 
    <input type="hidden" name="item_name" value="Something"/> 
    <input type="submit" value="Subscribe!" /> 

When I run this code it hits a page in my browser which I have not used in years, but it is mine and no longer in use.

Went looking for where I could set this return address and found this:

If you wish to have the default AutoReturn URL, follow these steps:

1. Log in to your Premier or Business account
2. Click the Profile subtab
3. Click the Website Payment Preferences in the Selling Preferences column
4. Click the On radio button next to the Auto Return label
5. Enter the URL where you want your users to return in the text box labeled Return URL

My account is not a business account, nor a premium account though it may have been in the past. Anyway I cannot find this setting, where is it at and how can I get the default AutoReturn Url changed?
