If the LPC2106 sees that the program is validated (checksum in 
Interrupt vectors correct) it will start and the program will crash. 
This will happen every time and so the chip will not go to ISP mode.

Have you pulled ISP Pin P0.14 to GND and reset (or reapplied power) 
and then tried to communicate with the FLASH utility. This will 
force ISP mode and it should be possible to load the correct code.
