After a 4th attempt I just gave up. contacted microsoft support over the phone today and was told I should call back later where technical help would be available. Mine doesnt stop for a while at 15% and continues later on it simply crashes at 15-16% the error i get is in the description. I have tried disabling my anti virus, unplugging anything to the pc but my mouse and keyboard. Nothing really helps. I begin to suspect some files for some reason are corrupted or something. Preventing the transfer.
