Error "10010" Randomly.

Santivi1457990

I played LIVE quite a lot and enjoyed, but one day I logged onto Live and on the starting screen it popped up a message that Pokemon TCG Live could not be loaded. I am in the UK which is now a beta authorised country, because I have been told 10010 is to do with location error, but I am in the right country. Lists of things I have tried:

Logging on another device (worked)

Deleted and Reinstalled (About 3x times)

I am considering doing something major like reinstalling my OS but that'll delete all my apps and my settings that are already preset. Is there anything that could be done as I am a supporter of LIVE and want it to do well but I can't see it do so if I cannot log into the game.
