Hello mickymcglinchley
Thanks for taking the time to contact us via the forums and welcome to the community! In regards to the TV Go registration issues, we can understand how frustrating this can be.
We have recently made some changes that should have resolved this issue. We have reset your device allowance today and if you could monitor this going forward and let us know if you have any further issues in regards to registration and reaching the device limit.
Thanks
Rob
