Hi,
 I know this is far stretch but I had similar problem with another 
LPC2000 chip and diference was in RS232 chips . STMicro ( MAX3232 
equivalent ) was not the same as MAXIM or TI equivalent. The same 
syndrom - ISP would not download code - otherwise all serial 
communications were OK.
 Radim.
