It looks like your last two sessions, attempting to stream Crazy Taxi on the 14th, were on Wifi and there have been no attempts since.
Did you get a different error when you tried to stream wired? If so, what error was this?
This forum is for technical support. We do not have the ability to provide a refund.
But if you would like to use the service, you can try hooking the device directly up to your router or modem (instead of connecting over Wifi) and see if that works.
