Heroes 3 Restoration Of Erathia. Help!!!! (Heroes of Might and Magic 3: The Restoration of Erathia)

There is a problem, I have no idea how to solve it. Downloaded from the Internet Complete collection of Heroes 1-3. To a greater extent for 3-parts. Played normally until I reached the Renaissance Erathia, the Echoes of war. When trying to start a company, I just throws on the desktop. I have different sites rocked, even bought a license - the problem is the same. I can't go this company and can't complete the game.
Before, on Windows XP everything went without problems. Now stands 7-ka. Help, someone, please!!!!
