Bms file is used to unpack evp file.
Older file was opened early.
But the file cant be used more for new evp file.
I want to discuss about this with some guys.
I have good idea.
Please contact me.

Do u know about script for decompressing your packed file?
As aluigi said, you must see the document.
The older script is opened already.
But new bms must be used for new packed.
