Campaign file error

I keep getting this message:

(((campaign file error!

Please verify your game files and try again.)))

I was playing the game yesterday and then this happened today for many of my purchased games.

I can’t post pictures here because I’m a new fourm user!!!

I have the same problem. I could play the game last week but now I cannot play Alexander the Great or Battle for Greece.

I am at #177723, and other DLCs seem to be fine (except Victor and Vanquished). This sounds like another system bug to me, given this is not the first time some DLCs I have owned for years all of a sudden disappeared.

Please help!

Humph, now they all come back. Well, I suppose it was a server side error. Note to myself and others: apparently the Microsoft servers are not as reliably as I hope they should have been, given they have been there since decades ago. Now I have to restart from square 0, given I diligently tried resetting the game progress…

I am still having this issue. I have uninstalled and re-installed the game and DLC to no avail. Same error message as above.

I have tried on 2 separate PCs but with same results.

I play through the Xbox app
