Some bugs can be really irritating and frustrating for everybody. But now the button works correctly so here is the instruction how to renew your membership.

Log-in with your membershipnumber and passcode on the homepage.

Then click on the homepage on the button 'Sign up here for your membership'.

You are redirected to the membership information page. But at the top of the page is the text 'Click here to renew your membership.'

Click here and you are on your Profile Page. On the right hand side you see the button 'Renew your membership'. This will direct you to the Paypal secure server. After your payment, the data is transferred to your new 2010 profile Page.
