how to change font

[wwwwww]

I build a font upk file，and change DefaultEngine.ini like this：

 

[Engine.PackagesToAlwaysCook]

; UI Font madness

+SeekFreePackage=gfxfonts_kr

+SeekFreePackage=gfxfonts_jp

+SeekFreePackage=fonts_test

 

but I see log：

[0007.11] Warning: Package '..\..\XComGame\CookedPCConsole\fonts_test.upk' has been saved with engine version newer than current and therefore won't be possible to save. CurrEngineVersion: 8916 VersionSavedWith: 10246

 

I need some help。
