ICD programming PIC16F874

[Vovachess]

Hello.
I have problem with ICD-U40 programming of PIC16F874-
I have the simpliest programm:

#include <16F874A.h>
#fuses HS,NOWDT,NOPROTECT,NOLVP

#use delay(clock=4000000)
#use rs232(baud=9600, xmit=PIN_A3, rcv=PIN_A2)

main() {

while (1) {

output_high(PIN_D0);
output_high(PIN_D1);
delay_ms(1000);

output_low(PIN_D0);
output_low(PIN_D1);

delay_ms(1000);
}
}

I can programm MC with ICD but software goesnot run. Even occilator diesnot run. I looks like problem with fuses or LVP.....
What could it be?
Thanks

.
(2) Did you select PIC16F874 or PIC16F874A in your header ?
I use PIC16F874A header

(3) Does the Reset pin keep close to 5V while running ?
Yes

(4) Did the hardware run properly once at least ? If not re-chek the OSC capacitors.
Yes

(5) Regarding the FUSES i will try
#fuses XT,NOWDT,NOPROTECT,NOLVP
Tried....
It does not run
