James,

 Regarding PORT E, make sure you go into ADCON1 (IIRC) and change the
 pin configuration to digital I/O.  They power up an analog input for
 the AD Converter.

 Regarding PORTD, if PORTE is setup wrong, PORTD will won't react
 correctly I think.

 Hope this helps you out.

                                                 Regards,


Jim
