After uninstalling and installing the game it fixed the issue, but it would be nice if you guys check the Warhammer.exe in the Steam repository, as I tried to move that filie and the other .EXE in the folder and use the "Vertify Game Integrity" and it only downloaded the Prophecy .EXE but not the bigger file, hence I had errors about missing files.

That might be the cause of the issue because it seem that Steam didn't download the new version of the bigger file, only the small one.

Since it only happened with few people, I'm wondering where the issue really is, as fixed by only verify the files, mine seem to be the extreme case so far.

It doesn't, I tried 2 times, the first normally.

The second I moved the 2 .EXE files in the game folder to somewhere else and did the checking, Steam only downloaded the smaller .EXE and when I tried to run the game it gave an error saying a file was missing.

I restored the bigger file and ran the game normally but still give the version error.

I already restarted Steam, the PC, my router and internet, now I uninstalled the game and am downloading it again.
