Are you sure you have the ICSP circuitry connected peroperly? Could you show us your schematic and a photo of your setup? Having these might help us diagnose the problem.

Also, check your setup against this:

That looks like a faulty wiring as DerStorm8 has pointed out, its obviously a common mistake, Check for any dry soldering and check every pin reach the PIC controller (continuity).

Also just check the voltage check box.... If its under 4.2 ( brownout) it will not work..
