Mana is not displayed on the combat field – This issue occurs after upgrading from version 3.0 to 3.2.

What are you talking about? Did you even check the link? It's some kind of garbage; please remove it. Here's my map: http://phomm.narod.ru/sodexe.zip. It should work without the disk, and I don't have any mana issues (but mana and similar problems might be due to text files in the game's resources, so look for them).
