Human interface device service is stopped

I cannot activate the Joystick in FS 2002 (it used to be OK, but i have not
use it for a while so I do not know what caused this) ,However I think the
problem is related to HID because the service is stopped and I cannot start
it.
I receive the following message:
"Could not start the human interface device access service on local computer
Error 2 : The system cannot find the specified file"
What I have already done /checked:
1) copy hidserv.dll;mouhid.sys; mouclass.sys under c:\windows\system32
2)the files hidusb.sys ;hidparse.sys ; hidclass.sys are under
c:\windows\system32\drivers.
I'm running WinXP SP2
Thanks in advance for your help
