You mean that last month you bought your first €12.99 membership plan and also paid the €12.99 one-time activation fee but this month when you go to buy your second €12.99 membership plan it's asking you to pay the €12.99 activation fee again?
That's very odd.
The one-time activation fee should be just that - a one-time charge.
Can you post a screenshot or clarify what exactly the site is saying?
You'll probably have to contact 48 support for assistance with this.
