Help with save map

[EvanDavis]

Hi.
I would like to ask for help. I am a beginner in this world editor stuffs. I downloaded a map from here.
I would like to make some changes to it. However, it won't let me save it because of an error.
If i don't make any changes on it, it won't let me save it either.
Can you help me? I'm complete beginner, how I can solve this problem so that I can modify the map later?

Original Warcraft III + TFT, (1.27) downloaded from my Blizzard account.

Hello, so the error tells you what's wrong:

Issue: Player Buildings: 612 placed, 600 allowed.

It also tells you how to fix the problem:

Solution: Please reduce the number of objects in order to save this map.

So you have to delete at least 12 buildings from the map (612 - 12 = 600).

That aside, I've never seen this error before, and it sounds like some limitation with your version (1.27). How about upgrading to a newer version like 1.29 or 1.31 or even the latest patch? The map's recommended version is 1.29.
