Campaign saves not loading

[Goth]

This is a new one on me. I have just upgraded my computer and am playing M2TW Steam version for the first time, also it is the first time I am playing in windows 10 having always played in windows 7. But now I cant load any saved campaign games, even the ones I have just saved in the new install. All the game does is display the spinning hourglass.
Anyone come across this problem before? The Steam version is the definitive edition and its windows 10 1909
Many thanks

Please upload a save here - that way we can establish if it is your save or your installation.

I reinstalled M2TW and its still doing the same, but its not the save games that are corrupt as its doing it with all of them. One thing I have found though is that if I press Alt+Ctrl+Del and then cancel it goes back to M2 and the loading starts. So now I at least know that I can load my savegames and having to press Alt+Ctrl+Del is not a great effort. But it is a strange thing I have never come across before.
