this application has encountered a critical error:
the file data is corrupt

programL d:\warcraftiii\war3.exe
fil: Sound\Music|mp3Music\NightElf1.mp3


Press OK to terminate the application

ad yg tau itu kenapa ?? takutnya ad salah ga sengaja delet data atao gimana gitu

Repatch / Reinstall client. Soalnya ada data yg corrupt.

bongkar ja MPQ nya.... terus replace file "Sound\Music|mp3Music\NightElf1.mp3" sama file yg sama tapi dari komputer lain.
