The "incf  portb"  *could* be a problem. Try the following :

In the CBLOCK add a new variable, let's say "portb_tmp".

Then change :

>          clrf counter
> again:   incf  portb          ;"f" is default

to :

>          clrf counter
> again:   incf  portb_tmp, w
>          movwf portb

Just a warning...

The cause is here :
> again:   incf  portb          ;"f" is default

Note that the comment says the same thing as the message :-)
