Hi,
there have been nationwide issues with VM activations since Friday. Some forum members have reported that theirs is working now, so it may be that it will fix itself. You could try rebooting the equipment again. Broadband activations were having the same problems but have partly been restored.
There is a sticky post in the broadband section along with a fault reference number QuickStart-set-up-and/Equipment-Activation
EDIT
tIn the meantime you may be able to stream live TV and on demand content, also Sky Cinema using the TV GO app
