Disabling LVP in your code is not sufficient.  It get re-enabled when the
programmer does a bulk erase, and cause trouble during programming until it
eventually gets disabled again when the config bits get written.  You need
to make sure the PGM pin is low during programming.  100Kohms to ground is
often a sufficient fix, depending on the external circuit of course.

There is more about this and other programming issues at
