Map Editor: Problems and Solutions

Can anyone help? I have Heroes 3: Armageddon's Blade. In the map editor, half of the objects don't have descriptions, and, worst of all, the Artifacts tab in the map specifications is EMPTY. It says "Enabled Artefacts:" and then nothing. Because of this, I can't assign an artifact as a quest item for the Seer's Hut. I need to choose it from a list, but there are no artifacts in the list. When I check the map, it says that all artifacts are reserved. But if I scatter them around the map, everything works fine in the game. WHAT SHOULD I DO???!!!(((:( :confused:
