HI everybody,

I've got a problem with 18F452 and picstart plus.

-PIC18f452
-PBP ver 2.45
-MPLAB ver 6.61.00.0
-MPASM ver 03.80.03 all setting to DEFAULT
-PICSTART PLUS with upgrade kit and firmware ver 4.30.1

after compiling program with MPASM ( no error reported), i load it in MPLAB ( file/import/program v100.hex) and i obtain this error message:
"the format of the file C:\...\program v100.hex can not be read or written because its extension was not recognized"
can someone help me?
