The error CS1011 means your box is currently unable to load your account data due to a provisioning problem on the server side. You could try to unplug your modem and your TV box from the power grid for 30 seconds and plug them back in.
If the issue persists you best contact the hotline (0800 707 707) as they can check your account accordingly. Alternatively you can use the Contact form | Support if you prefer a written request but response times are not known to me.
