Series link broken after replacement 360 box.

Hi, I have similar problems to others on this forum, just upgraded my V6 box to 360 software, no problems for a couple months, then had fault in box and Virgin replaced it with new one. One issue I have is some series links don't work which were setup on the old broken box, when I try to set these up a get error message:- " Sorry, we couldn't do this for you. Please try again later" Setting up new series link to other channels/programs no problem.

I also tried Virgin Go app, similar problem, error message:- "Action not possible, your box is offline, Please turn on and try again." Again setting up new series link to other channels/programs no problem.

I have tried all suggestions in this forum, Reboot HUB/boxes, restore factory settings etc no luck? It seems to have some link to the broken box, how do I get this sorted?
