How to play the campaigns in the standard version of Heroes of Might and Magic V, specifically the Tribes of the East expansion.

Excellent!))) Although I found the link myself, I had some problems with the installation. I want to note that if people are asking about it on the forum, it means they really don't know how to install mods. It took me a while to figure out that you need to create a folder called **UserMods** in the game folder; what is obvious to some is news to others. I installed the mod and was able to play it, but now there's another problem: if I go into the Modifications menu in the game and load a campaign there, the list of campaigns in the modification menu shifts down, but without the mod, everything is fine in the original game. It seems like two mods are conflicting; is there a way to fix this?
