This sounds more like a fault than a subscription issue.
Is there a flashing light on the front of the box?
I have located your account to send some signals down to your box so would you be able to turn the box off then back on by the mains for me please?
Also another step to try if this doesn't resolve it is to manually connect the box to the Virgin Media network, you can do this by going to -
Home - Help & Settings - Settings - Network - Connect to the Virgin Media Service Now
You will then see another screen pop up which will go through different stages, you don't need to keep this on your screen so if you press the TV button at the top right of your Virgin remote it will remove everything off the screen and continue to work in the background which can take up to one hour to complete. but please let me know how you get on after the forced connection.
