Xbox live problems on W8

Is anyone else experiencing problems with Xbox live in W8 (Asus T100)?

Problem is that it keeps logging out (after every restart and than some) and live tile is not working.

I don't really use xbox live that much, but if it's there, I'd like it to work properly. It's annoying when MS Mahjong keeps reporting errors every time when I open it.

Is there a solution?
