Says it cant find save and calls my disc lite version need answers

I would say that you need to uninstall downloaded version and then put the disc in and let it install from disc. Don't worry about your saves, they have backups on cloud.

well if you playing the digital version from the marketplace you will not need the disc but if you are playing a version of the game saved to the hard drive from the disc, you will need the disc in there if playing that version of the game, but the marketplace
one a disc is not needed.

Thanks for your answer.

I was just wondering why you need to download the whole Xbox 360 game again though you've got the disc to install it.

If you're saying that you need permamently internet conncetion just to start/play and save games to the cloud why there is a xbox feature which you can play OFFLINE Games and save games locally at first place?

For my point of view it doesn't make any sense that you need "permanently" internet connection just to save current progress to the cloud.

And yes in Xbox 360 it's different because it has never asked me for internet question before I can start/play an offline game (disc or digital version) and I could save my current progress locally.

Activision should come out with a Call of Duty Mobile version called Call of Duty Lite. Most people who are dedicated to their PC would prefer such a game to be played on PC instead of playing on a Cell phone or I-pad.

They really need to stop bs-ing and get with the program and work with Microsoft so they can make it happen.

I have the call of duty mw3 as a disc

You will just need to request a refund on the vault upgrade then.

As stated by ngocphi it says in the description that the digital version of the base game is required.

It wont work if you are gamesharing or have the disc version.
