Hi all,

I have a great problem I can not able to fight. After checked that my PIC16F877A is not blank (using command Blank Ceck All), I tried to erase it and program it.
It seems that PIC has a code protection flag that doesn't allow the PRO MATE II to program it.
The message displayed is:

Program memory/IDs are NOT blank.
Configuration memory is NOT blank.

May anyone help me to solve this trouble?
Thanks a lot
