Thank you for your help, however when i log into the service on my laptop, it registers a device and then doesn't let me watch anything. When i return to the service it allows me to register a device in another slot but again doesn't let me watch anything. I have overwritten one of the used slots with my phone which works perfectly fine
This happens when i use the Chrome browser, i havn't tried any others for fear of locking up device slots unnecessarily.
