Thanks for contacting us over the community forums.
Sorry to hear that you're having issues with the TV go service on your PC, the TV go app needs your cookies to be kept from the time that you register the device, if you clear your cookies it will require you to register again. There is more information about this here.
Have you been able to get this looked into further since you last posted? If not, I can look into this further for you and reset your TV Go devices.
No, I havn't had time to speak to virgin and get my device's reset and would be grateful if you would do so.
Interestingly this forum question is running at 17 pages as of today. Lot's of frustrated customers perhaps you could escalate to review how this app works. I apprecaite it's as expected but reading through the responses I think that there are some deeper issues.
