HAVE TO RESTART FROM MAP 1 THIS IS THE THIRD TIME I HAD TO START OVER...WHY?

SORRY FORGOT TO TELL NAME OF GAME ULTIMATE WORD GAME

I much prefer the second over the third. I actually have the third disabled.

I had the second and third disabled for a while, but recently re-downloaded the second.

I don't play zombies, so my opinion on those is moot.

The only map I don't particularly like out of the second map pack is Convoy. But it's not a terrible map.

I restart games all the time. Either you will do it or you won't. I've gotten to the end of Final Fantasy X three times without beating it and started all over from scratch. But my reasoning is not the same as to why you have too.

Spoilers: If you want to save the ship crew, you can not do any missions after activating the IFF. 1 to 3 missions, half will live. 3 and over, all but the doctor. Spoilers

The last map pack that was released had an update to go along with it. After that update was applied everyone had to re-download their previous map packs/content for MW3 and if they had played Spec Ops they were reset to level
1 all over again. What you need to do is load the game and enter the Store from the MW3 menu and just re-download all the map packs you had before, don't worry it will only takes seconds for each one. When I did it the console had to be restarted several times
before the downloads were completed. So in all it took about 10-25 minutes (I also had to download the newest map pack which took some time being release day and all).

Let us know if this solves your issue.

I am stuck at the same place, after completing the area and exiting back out to the sands area it is stuck telling me to go back to the entrance of the Warrens. I have played through it 3 times, tried restarting the game a couple of times but no change.
What is really frustrating is that this is the second time it has happened, the first time was when I met Kai. I started over and was able to progress through that point, but not sure that I want to start the game over again for a third time.
