If you are having any issue related to the product key then first let me know where you purchased this game. If you have purchased it from some local shop then you might got the pirated version of the same which does not having the proper product key and it uses the cracked version of same. Also it is better to replace the copy of the same with the new one which is having the valid product key. If still not getting anything work with the issue then i will advise you to contact the Microsoft regarding the issue which you are going through and ask them about then solution for same. So if you can then go through the same and find it working with the same.

Failure of a film star from Hollywood flavor, Niko Bellic is a perfect example of excellent narrative view that the boys at Rockstar have managed to pour in every hidden corner of the infinite lines of dialogue, which make up the fascinating story of GTA4.Over time we will feel part of the drama of a past of war that marked the character of Niko heavily, we will discover the difficulties of a family shattered by crime, we get attached to a brother a little 'inept and clumsy and we will literally caught in the evolution a narrative plot grim, bloody and very ripe but with a strange taste of healthy realism, even daily, and we were struggling in the first person with the most serious crimes of society.
