Both,
I've now got it working again. These are the steps I took, not all of them may be necessary.
On Virgin, I have a separate modem and router setup, not a Super Hub.
I went into the Lovefilm website on my computer and deactivated my S370 as a device.
I converted my Lovefilm account from a Lovefilm sign in to Amazon - which needs to be done soon anyway, they should have sent you a mail about it recently.
I did a factory reset on my wireless router which reset it's MAC address which forced a new IP address from the modem/Virgin. Had to set up my wireless network again which was a bit of pain but there you go. I read this was a solution on another device on the internet so thought it was worth a try. Before doing this, if you are using the Netgear router from Virgin, log into it first using the 192.168.1.1 address, look through the settings for the MAC address. If it is set to the default address, you can probably skip the factory reset. Instead, change the MAC address shown to something else. Wait for the router to restart then you'll need to turn your modem on and off (30 sec wait) and this will force a new IP address from Virgin. i think the IP address is the key here. If it doesn't work after following the steps below, try the factory reset.
I then managed to get into Lovefilm on my S370 but it was slow. I then signed out of Lovefilm on the S370.
Finally I did a full factory reset on the S370 and initialised personal information on the S370, turned it off and unplugged it for 30 seconds. This should clear out the internet content listings on the video column.
Plugged back into, reloaded all internet content, went into the Lovefilm app, signed back using Amazon credentials and it's all fine now.
Bit convoluted but has done the trick! Good luck!
