Great News! And you're welcome.

I'm not familiar with the K128 ...
But with a quick look at the schematic in the datasheet, it seems to use a series of diodes and capacitors to increase the voltage and applies it to VPP.

They have several different programmers.
The LVP comment might have been directed at a different product.

But when LVP is enabled ... anytime RB5/PGM goes HIGH ... it's just like taking MCLR/VPP to 13V.
If it's left floating, the PIC could be constantly entering Program Mode from input noise.
