Oh finally! I got it, I re-installed the mod again and it works!
Everything was right installed, it was that the mod files were missing. I erased the mod and downloaded it again, did same thing-(now nothing was missing)-and I got it working. Maybe when I downloaded the first time, I turned off my pc, then the download was un-finished. Not all files were downloaded which caused the problem of missing files and the mod not working. Now it works well. But I still noticed something wierd... there are 2 or sarumans on battlefield! Is it only me, or is it a general bug?
and thanks for tips, ArtyomtheGamer
