Yes you are right...0Vcc:) Anyhow, I solve the problem and now everything is OK. I hate to say but I must recognise that was my fault. I count PIC's pin as follow: From the key left up to down pin 1 to 9 and from the left up to down 10 to 18...instead of 18 to 10:(((( My luck were that VDD and VSS are in the middle so doesn't matter from were you start counting, you can't broke the chip instead of switching + with -. Programmer is OK, blinking LED project is working, also Flash LED project(with 8 LEDs)is working and make some "tunning" on it:) addapt the timer routine to 4MHz qurtz. Now I'm ready to learn and try PICs programs. Thanks to all who your help me.

Being paranoid is good for a programmer (actually for any kind of engineer). I would trust the programming only if I can read back the content of the chip and it matches the original .hex file exactly. > - pin 5 to -5Vcc. I hope you mean 0 Volt? A difference of 10 Volt is not healthy for a PIC!
