[Help] Can't change maximal lvl

[kartons]

Hello, i have a problem with max level.
In my files don't have option change max level. But i find tutorial http://forum.ragezone.com/f196/max-l...000-97d-77500/ .
I can't find with hex "4. Change this: 81 7D F0 90 01"

90 01 - 400 lvl.

Serverfiles is season 4.
Thanks.
