Well no as you bought the wrong version

The 30 dollar upgrade is meant for buyers if the cross gen base game

You would have to buy the base game or buy the full 100 to platy

Vault has 2 versions thr upgrade 30 dollar version which requires the base digital game

Vault edition the 100 dollar on sale atm which includes full base and vault upgrade

Hi, my name is Marvina and I will be happy to help you.

I'm sorry you have this problem, researching on the internet I was able to find that in the forum, the independent advisor Gerardo, recommends the following steps for a solution.

I understand that you are having trouble accessing Zombies mode in Call of Duty: Modern Warfare 3. The error message "sys_error disk rollback error [8.7]:'ww_mp_jup_bigmap.ff'" indicates a problem accessing a game file specific. These are some of the possible solutions you can try:

Check the game files:

Most gaming platforms offer a feature to check the integrity of game files. This tool scans for missing or corrupted files and replaces them automatically.

For Steam: Right-click Call of Duty: Modern Warfare 3 in your library, select "Properties", go to the "Local Files" tab and click "Verify the integrity of game files... "

For PlayStation: Insert the Modern Warfare 3 disc, go to Settings > App Saved Data Management > Saved Data in System Storage > Delete > select the Modern Warfare 3 data and choose "Delete".
For Xbox: Go to My games & apps > Manage games > Modern Warfare 3 > Uninstall all > select "Keep game files" > Reinstall the game.

Wipe the game disk:

If you play on a console, make sure your Modern Warfare 3 disc is clean and free of scratches or dust.
Gently wipe the disc with a soft, dry cloth in a straight, radial motion from the center outwards.
Avoid using harsh chemicals or abrasive cloths as they may damage the disc.

Update the game:

Make sure you have the latest updates installed for Modern Warfare 3 and your gaming platform.
Outdated versions can sometimes cause compatibility issues and bugs.
Check for updates through the game launcher or the console's online store.

Reinstall the game:

As a last resort, consider uninstalling and reinstalling Modern Warfare 3 completely.
This will ensure that all game files are up to date and will hopefully resolve any corrupted data issues.

Hi hope you have fun in xbox message me if your interested in playing Call of duty or RPGS or Zombie games.

This is why they need a call of duty for kids! And a cod game for the older crowd! I don't really like the whole 25th killstreak thing, its an Iw item and I hope it stays that way. And I hope they never link zombies with what has been separate to this
point online multiplayer! No killstreaks that allow zombies, that's just kiddish, This is also why they need a zombie game separate from the traditional military call of duty style game, it has turned into a childish non realistic game.

Call of Duty: World at War doesn't count. Zombies man.
