Hello I had this problem to if by any chance you guys have an Xbox360 to hand you can fix this hears how.
1 Setup your 360 to your tv
2 Connect to your internet connection sign in with your account
3 Goto settings then to family tile in there turn all of the settings to on make Sure everything in on ie alow all game alow all movies also make sure the unrated option is on make sure that everything in their is alow all and some will be on or of turn them on.
The next thing after all that’s done you will have to make a four numbered pass code once done save the changes you can not save these settings until pass code is done so just make sure you do the pass code easy to forget.
That’s all there is to it then go to game on your PC goto the gifts tab click on one by one gift they all should download now
PS if no 360 to hand you may have to contact Xbox live support for more info and help.
