I did not answer your question, I thought you are talking about signing in games (the post above you was talking about games)

I had that problem yesterday; install fine, but wont let me sign in. 2 options

1) touch 4 corner clockwise will take you out of the sign in wizard, try empty space corners.

2) scroll down to bottom, there is an option to 'tap to skip sign in wizard' .....AH!

sorry about the delay response, I thought you are referring to those games which I have no idea how to sign in or what not, hope this helps, buddy,
