F.E.A.R. keeps crashing

[Komandant]

When playing, the game will suddenly crash at certain parts. I noticed that when I look at the floor, and can't see anything but the floor, I can get through parts without it crashing on me. That is a bit of a pain but I can deal with it I guess. The big problem is when it crashes during parts of the game that I can't control the camera with. The engine message file kept displaying things like,

GENERIC_ERROR = "Internal FEAR.exe error: %1!d!."
MISSINGWORLDMODEL = "Missing WorldModel: %1!s!."
CANTLOADGAMERESOURCES = "Can't load game resources in %1!s!."
CANTINITIALIZEINPUT = "Can't initialize DirectInput."
UNABLETORESTOREVIDEO = "Unable to restore video mode."
USERCANCELED = "User canceled."
INVALIDWORLDFILE = "%1!s! is an invalid world file."
MISSINGMODELFILE = "Missing model file %1!s!."
INVALIDMODELFILE = "%1!s! is an invalid model file."
MISSINGSPRITEFILE = "Missing sprite file %1!s!."
INVALIDSPRITEFILE = "%1!s! is an invalid sprite file."
NOGAMERESOURCES = "No game resources specified."
MISSINGWORLDFILE = "Missing world file %1!s!."
CANTRESTOREOBJECT = "Unable to restore object (class %1!s!)."
SERVERERROR = "Server error: %1!s!."
INVALIDOBJECTDLLVERSION = "Object DLL %1!s! is an invalid version (%2!d!). Current version is %3!d!."
INVALIDSHELLDLL = "Invalid shell DLL %1!s!."
INVALIDSHELLDLLVERSION = "Invalid shell DLL version for %1!s!. DLL version is %2!d!, current version is %3!d!."
MISSINGSHELLDLL = "Missing shell DLL %1!s!."
CANTCREATECLIENTSHELL = "Can't create client shell."
UNABLETOINITSOUND = "Unable to initialize sound system."
INVALIDSERVERPACKET = "Got an invalid server packet."
MISSINGCLASS = "Missing class: %1!s!."
ERRORINITTINGNETDRIVER = "Unable to initialize network driver %1!s!."
INVALIDNETVERSION = "Network protocol version mismatch - your version: %1!d!, server's version: %2!d!."
CANTCREATESERVERSHELL = "Unable to create server shell."
ERRORLOADINGRENDERDLL = "Error loading render DLL %1!s!."
ERRORCOPYINGFILE = "Error copying file %1!s!."

I don't know if that helps but it make it seem to me that there is something wrong with the engine maybe?
