Hola,
hace mucho tiempo que no me paseo por este subforo, pero ocasionalmente lo hago.
Se tiene la licencia del PBP (2.50c) y se realizan simulaciones (y compilado, claro está) en MPLAB directamente; al parecer se pudieran tener problemas debido a esto (directamente de microengineeringlabs.com):
Technical Support
(01/26/2009) Microchip's MPLAB version 8.15a appears to be the last version that will support COD file functionality. This means that PBP will generate errors in MPLAB version 8.20 and later.
We will be releasing a new version of PBP with COFF file compatibility in response to this surprise move by Microchip. In the meantime, MPLAB version 8.15a is available for download here:

Interesante, solo para que lo supieran.
