If you erased it, then this is what I would expect.  Read it before
erasing it.  If it's too late, then bad luck.  Either buy another one,
or ask around for the procedure to re-create it using a test jig.

No.  It should go at the last code location as described in the data
sheets.  The instruction should be the "movlw" there, and the "movwf"
should be at 0x00.
