- Patches for Heroes 3

Hey everyone, I have a problem: Sod AB and WoG are installed in the same folder, and all campaigns are displayed in the game, but AB doesn't work – when I open the campaign selection window and choose a campaign, it starts an endless loading process. After 2 hours, it gives an error saying that the disk is missing, even though it's there. All game versions are licensed, so why is this happening?

Before installing SoD, everything worked fine...
