请问哪位帮我一下啊！我1运行cso nst就出现标题是Fatal Error，内容是Error 5899: Metadota file missing or damaged [-1]!!!,请问这是怎么回事

Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Valve\Half-Life\Settings]
"EngineDLL"="hw.dll"
"User Token 2"=""
"User Token 3"=""
"ScreenWindowed"=dword:00000000
"CrashInitializingVideoMode"=dword:00000000
"ScreenWidth"=dword:00000400
"ScreenHeight"=dword:00000300
"ScreenBPP"=dword:00000020
"EngineD3D"=dword:00000001
"ValveKey"="5RP2E-EPH3K-BR3LG-KMGTE-FN8PY"
将上述字符复制到【开始】——【附件】——【记事本】里，保存为任意名称.reg
注意，文件后缀必须是.reg！
完成后打开，点击确定就OK了
