Game.exe and EP3 Mix 12 Client!

Hi, I just downloaded RAN EP.3 Mix 12 client (unpack - there are a lots of EP.12 armors and weapons) so I can't copy Data and Paste to my EP.3 private server? Game.exe always says NEED NEW VERSION EXE FILE??? Does EP.3 has another version of EXE file?? (I cant see EP.3 source here!)

So... How can I get the new version of EP.3 exe files? What's about the update??
Can I copy EP.12 textures to my EP.3??

and I amnot understand, If we pack the Glogic/Param, How can Game.exe read those files?? Can player unpack it?

Sorry for bad eng, I am THAI.
Thanks in advance.
