Lpc2000

I need to help with programming LPC2106 via LPC2000 flash utility. I've got board with one LPC2106 connected via UART0 to COM1. P0.14 is pulled low, power supply pins are in limits but I can't sucesfully connect with flash utility. Always I get message "Cannot communicate with test board". X1 and X2 pins are connected to 7.3728MHz resonator. If I measure data between PC and LPC2106 it has some response on flash utility requests, but no success:-( I had several pcs of this hardware working, but this one doesn't work. I've changed LPC2106 with new one but still with the same result.  Does anybody have idea how to fix this problem?
