The difference is config word settings.

The first hex file created with PBP 2.33 has internal osc, mclr off.

The one created with the demo version has XT, mclr on.

When you install the demo it includes different "default" config fuse settings
in device header files installed in the PBP demo directory.

Change the demo version default config settings by editing the device header
file, or simply change config word settings with your programmer before
programming the target.
