Your .HEX file work for me, nothing really bad in your code. Double check your hardware and if your universal programmer is set to program the configuration fuses.
 
thanks for the check , but i dont know how my universal programmer works with PICs ... i posted a pic of the configuration , would you check it ?
 
I don't know this programmer and they seems to use a weird syntax. What happen if you click on the ReadCFG button?

Doesn't seems he read/updae the config fuses automatically when you load the .HEX in your software... well from what i see on your picture...

As pointed out by mister_e, it seems that the software is not configured to handle the config settings properly. Try reading the PIC as suggested; what value do you get?
The config word saved within the hex file is 0x3F7A (read with IC-Prog)
