Code error at 0000 means it is unable to modify the flash.  It tries to
write the first byte, verifies, and the verify fails.

I'm fairly new to this as well, but here's what i think it might be:

Are you using Low-Voltage programming or standard?

If you are using low-voltage programming, maybe your RB3 pin and VPP are
going high at the wrong times / in the wrong sequence?

If you are using standard programming, check that your VPP is actually in
spec while you are trying to write to the chip.

Also, is there any chance code protection was enabled?  This could cause the
error as well.
