Xbox warning sign not letting me play my game

Exact same problem for me. The home page says "technical problems" and will not let me sign in. Email warning was sent to me and CC'd to both of my sons.

^ Or they play a lot of COD...

Instant warning sign for me!

This warning is also associated witht he game refusing to let me log into my account so all my history is gone. I tried uninstalling and reinstalling the game to no effect. Plus signing out and then back in of Xbox. Neither had any effect. Actually it
is the exact same problem with the exact same result but the problem ID is [CV:id1OrQVq/EqLhESq.34.2]

You need to sign in again through the Xbox 360 interface assuming you're using Xbox One/Xbox Series, then it will let you log in. The game is filled with modders however so be warned.

I'd start by clearing the system cache (it's just temporary files plus game updates, automatically reloaded) by:

1) Tap the silver Xbox Guide button on the controller, go 2 clicks right to Settings, pick System Settings.

2) Select Storage (or Memory if Storage).

3) Move over any hard drive or memory unit (not the Cloud) & press (Y) on your controller & pick Clear System Cache.

4) When asked to confirm storage device maintenance, choose Yes.

Delete profile from your console

1) go to www.xbox.com/accounts & click on Sign in at upper right - if you can't sign in then
STOP: DON'T delete your profile. Please call Xbox Support
support.xbox.com/contact-us for help with your account. If you can sign in, delete & redownload your profile on your Xbox this way:

2) Go to Settings

3) pick System

4) choose Storage

5) pick All Devices

6) choose Gamer Profiles

7) pick the gamertag

8) choose Delete, and

9) pick Delete Profile Only. This deletes the profile but leaves saved games and achievements. Now, re-download your profile.

Re-download

1) Tap the silver Xbox Guide button

2) Select Download Profile (and if you don't see it, press the blue X button to make sure you're not signed in) and proceed with Profile Download.

3) Enter the Microsoft Account addresse for your Xbox LIVE gamertag when asked.

4) Enter the password for the Microsoft Account.

4A) If your account is an Xbox LIVE child account, the parent’s Windows Live ID & password is required as well to download your profile.

5) Pick the storage device for your profile (choose Hard Drive if you have one, or Memory Unit if you don't have a Hard Drive).

6) When the download completes you will be asked if you want the console to remember your password. If it's your home console, I'd say yes, otherwise I'd think carefully about leaving my profile unprotected on somebody else's
Xbox!

7) Sign in, and retry.
