TV Go App Registration (Win10 Laptop)

Each time I use the tv go app on my laptop (Win10) it asks me to re register my device even though I've registered it several times. This means I keep running out of changes and can no longer use the tv go app on my device.

The app is only registered on a Tablet, Phone and Laptop. Please can my devices be reset? I don’t know how solve this even following suggestions.
