On xbox x, version 0.1.2.1, I can't load a saved game. When I select the save and hit A button nothing happens. The only action tha I can do is back to mais screen pressing B button.

I had the same problem. Try do go to xbox settings > network > choose offline > jump back to the game > load a file (which should work now). after you are in the game go to xbox settings > network > choose online (cause this is what the game requires). go back to the game. It could be that you have to click continue game 2 or 3 times. 

I'll try this workaround. Thanks.

This work around works very well. Thank you for your help.
