Unable to load program to ATmega8

[shoeb.eee]

I wanted to program a ATmega8 with a test program but failed. I used ponyprog for this purpose.

When I waned to read the program (read all from command menu) it can read without any error.
When I load hex file and issue Write all command, it show progress bar but at last it showed Write failed.

What can I do now. I want your suggestion.

[Calibration is also ok]

First erase the flash memory then verify it. Does it work? If so, try to program the flash only. I have had similar problems using Codevision in some computers (not all) and after making a successful blank check it always works fine. Also make sure you have selected the correct device type.
