MMH5.5 - Heroes of Might and Magic 5.5

I read that new objects in the editor might not appear. Can I send the maps I created (16 maps) to someone so they can check if the objects from the mod are there, or if they didn't appear for me? I can send them via email. Or is this problem non-existent, and am I mistaken? I created these maps in July of last year. And is there a list available somewhere that shows all the new objects in the editor with this mod? I don't have the game installed right now, and I can't remember what objects are on the maps from memory.

I installed the game and the mod. MMH55_Mapmixer doesn't launch. It says that the Windows version is incompatible. I have Windows 7 32-bit. It used to launch without problems. What should I do?
