Although, sometimes the programming fails at half the percentage, but if I put my finger on the IC it resolves =D (not in the manual =P)

Finger on the IC, or on the pins (sometimes a finger causes both to happen)?
If its related to your fingers touching the pins, then you are likely acting as a 'decoupling capacitor' and you are either affecting a JTAG signal, or a power-rail.
Decoupling capacitors should be placed on every power pin. Ideally the capacitors go at the end of every pin, or are placed at vias directly underneath the power pins (or BGA pads).
