救命啊，第二章总是玩不了，出现mountappfilesystem()failed:

根目录下建了内容为hl2.exe -steam -game ep2的批处理文件，SteamEmu.ini的内容为[Options]
SteamAppsDir = ..\
; Used if UseCacheFileSystem = True

UserName = Unleashed
; This will be returned on SteamGetUser.

EmailAddress = Unleashed@owned-steam.org
; This will be returned on SteamGetCurrentEmailAddress.

Language = schinese
; Default language, if none is entered will be english.
; This entry can be used if the game is multilanguage!

MountOptionalCache = False
; This will mount optional cache files (Most likely these are low violence gfx)

MountCacheManual = 428
;With this you can manually mount cache files, but you will need the CacheID to mount optional caches.

CurrentAppId = 420 //Half-Life 2: Episode Two

SubscribedSubIds = 0, 501 //Steam, Half-Life 2: Episode Two Retail

游戏总大小为7,503,892,355 字节，解压解压那40多个压缩包得到13个GCF文件，和一个名为Half-Life 2 Episode Two的文件夹，提取13个GCF文件中的文件，与Half-Life 2 Episode Two文件夹中的文件合并所得，此大小游戏，然后出现mountappfilesystem()failed:错误提示，现在用的神翼杀手在圣城家园的BT包解压的，之前在电驴下载的那个版本也是这样错误，怎么玩啊？有人会吗？
