Error programming PIC Clicker

[MinnML]

Hello,
I am using a PIC Clicker from MikroElektronika with PIc18F47J53 processor.
I could easily use the tool to get the device ifo:

McuType: 'PIC18FJ'
EraseBlock: 0x400
WriteBlock: 0x40
BootRev: 0x1300
BootStart: 0x1e000
DevDsc: 'PIC Clicker'
McuSize: 0x1fff8

But when I tried to load some sample code even the hex files compiled by MikroElektronika, I got this error:

Any clue on what might be causing this issue?
