Hello, this is my first post here. I tried googling but nothing answers my question.

I have a Windows 8 tablet and on my main user account (same email as my Xbox sign in etc) I cannot add any payment methods at all. I've been on to support and they've tried to fix it and and I'm awaiting response.

Basically I just want to purchase games from the Xbox windows store and use them on my main account.
Is it possible to create another user account on my tablet with a new email and attach my payment methods and download it to my tablet, then switch to my main user and play the games? If it's possible would this work for episodic content in a game like Adera and such? Thanks.
