Thanks for your post and a big welcome to the Community
Apologies to hear you are getting this error code. Can you also include the error message you are receiving?
What OS is your device running too?
As well as deleting the app, which you've already done, try re-registering the device.
Using a PC/Laptop go to anywhere.virginmedia.com > My Profile > Device Settings. Remove the current registration by clicking on the Delete button. Once you've done this, using the device you are trying to re-register, open up TV Anywhere and log in. Try to stream Channel 4 and this should then prompt you to register the device.
If you follow the prompts on the screen, this will register the device for you and streaming should then commence
Let me know how things go.
