boom you can try what this guy did http://eu.battle.net/wow/en/forum/topic/5585789229
open C:\ProgramData\Xfire\xfire_games.ini back it up first then edit [5186_1] and [5186_2]
the guy on this link just removed some lines
[4216_1]
LongName=World of Warcraft
ShortName=wow
LauncherDirKey=HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Blizzard Entertainment\World of Warcraft\InstallPath
LauncherDirTruncAt=wow.exe
LauncherExe=World of Warcraft Launcher.exe
DetectExe=Wow-64.exe
Launch=%UA_LAUNCHER_EXE_PATH% %UA_LAUNCHER_EXTRA_ARGS% %UA_LAUNCHER_NETWORK_ARGS%
InGameRenderer[0]=D3D9
InGameRenderer[1]=D3D11
InGameFlags[0]=ENABLE_MOUSE|USE_DINPUT_MOUSE
InGameFlags[1]=ENABLE_MOUSE|USE_DINPUT_MOUSE
DetectServer=FALSE
Locale=WoW
GameClientDataType=WOW
to this:
[4216_1]
LongName=World of Warcraft
ShortName=wow
LauncherDirKey=HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Blizzard Entertainment\World of Warcraft\InstallPath
LauncherDirTruncAt=wow.exe
LauncherExe=World of Warcraft Launcher.exe
DetectExe=Wow-64.exe
