Can't Open Nightelf's Campaign Final Mission

I extracted the NightElf07 map and opened it in the world editor but unfortunately I encountered a problem. The message returned to me was

The application has encountered a critical error:

The file data is corrupt.

Program: c:\program files\warcraft iii\worldedit.exe
File: units\Orc\Thrall\Thrall.blp

I checked the Thrall Folder with MPQ Master and the Thrall.blp is present. So what exactly is the problem with this map ?

I also attached the extracted map in my post so that you can check it if you can open it.

I really wanted to study and customised that map and have fun with Archimonde and his minions. lol

I can open it without problems...

Have you tried other campaignmaps ? Have you tried reinstalling / patching?

I tried other campaign maps and I have no problems opening them except that one. Well, anyway I think I'm going to reinstall the warcraft.

i can open it without problems, too. but i have another question,
where do i find the other campaign maps, or how do i open them?
