I also see that you don't have a diode in MCRL protecting Vdd from Vpp. From the PIC datasheet, the maximum absolute value that Vdd can take is around 4.5 V. If the programming voltage, Vpp, is greater than 4.5V you might have damaged the PIC by no using a diode.
I don't see anything else that might be causing problems.
