From the PPX FAQ:
But I’ll ask @Philips_Support_N about this for you. If you can’t receive it unless you pay I’d suggest paying it and sending me the payment receipt via mail to support@screeneo.com, and PM’ing me the ticket number you get back from the support system.
Well, I got a few who said they could no longer even pay for it online after a few days had passed. But that’s not a clear waiving of the fees, they could still get charged via postal mail for instance.
