Lpc2000

I've been using the Flash Utility with no problems with a LPC2106, but
I just brought up a board with a LPC2131. 

All my signals on the PCB are OK, and I can even "Synchronize", set
the crystal, etc. using a terminal emulator. I've tried a number of
commands using the terminal emulator, and the thing seems to be
talking just fine.

My version Flash Utility V2.2.0 (which is the latest I've found) gets
the part ID and boot loader ID, then gives me the message "Type not
supported". I assume that type is "LPC2131", which is not, BTW on the
utility's drop down list. Anyway, it won't let me go any farther.

I'm stumped. Any idea ?
