The editor has stopped working; Windows is looking for a way to fix the problem. It's halfway there. I have a licensed version of Windows 7. Core-3 processor, 8 GB of RAM, GeForce GTX 1050 Ti, Heroes is patched and licensed. This is already my fifth computer, and it didn't work on any of the previous ones either, neither in XP nor in 10.

and look for the email address of the author "Guano." Try to contact him; he mentioned that he might be able to send you an editable version.

function arena_level_up_pl1F (hero)
MakeHeroInteractWithObject(heroname, "monster_arena1_pl1");
end;
Trigger(OBJECT_TOUCH_TRIGGER, "arena_level_up_pl1", "arena_level_up_pl1F");
And no one can help me; why isn't this nonsense working?
