Complete and utter garbage on SE's part. Playonline's billing worked for 10 years already, just fine, with the exception of last month.
No one know what happened, maybe a fraud happen recently and SE breaking they association with them, maybe playonline just turning the switch off because it is old, no one really know the real story and doubt SE will start explain they strategy. All we know is they droping playonline as billing system. The GREAT news is how you now able to pay in multiple way, the BAD NEWS is how is C&B only that take care of your credit card for automatic payment =\ But ive said it in many post, give time to SE to explore the market, and they might eventually add PayPal too as automatic monthly fee.

Until then is simple option, use paypal to load crysta if you don't trust C&B. [that was my option]
