Game Shutting down ?

[DRG]

Here is ( in part ) the report we are dealing with and if anyone has any ideas as to why this might be happening please feel free to share. FYI we suspected his anti-virus but he has reported the same thing happens when it is turned off

I've completly unstalled the game.
Then re-install it in this folder: C:\Games\Shrapnel Games\The Camo Workshop\WinSPWW2.
After that, I've upload and installed the patch: winSPWW2 V12 Upgrade (2019).
Then I've put my saved scenarios in this folder: C:\Games\Shrapnel Games\The Camo Workshop\WinSPWW2\Saved Games and continued my play.
After exactly 30mn the game shut down without any message: it freezes and then shuts down and disappears!
To be sure of the reaction of the game, I've NOT saved during this half hour.

I have thought perhaps this might be an issue with the old saved games but he reported that the game worked OK as a DL version of WW2 but now he reports the DL version of MBT does the same thing
