zvuk270, judging by the screenshots, you have a version that's like "Heroes 3 + all known and unknown mods + even more stuff on top of that," and it probably weighs in at more than one gigabyte. In such a mess, few people (except for the modders themselves) will want to sort through it. It would be better if someone gave you a link to a normal version of "Heroes 3" via private message.
As for maps, after installing a normal version, you can check them out here and also here:
