error while downloading hex file to lpc2478

Dear All,

I am teaching an embedded systems course and it is the first time for me to use the KEIL NXP LPC2478 board

I have followed the steps in the board’s manual to download the “blinky project” onto the board, but I get this error:

“invalid hexfile directive (#H,NOCHECKSUMS,NOFILL,PROTECTISP) !!”

I would strongly appreciate it if somebody can help me out of this. Here are a few details:
Device: KEIL NXP LPC2478 EVAL BOARD.
PC OS: windows XP
Keil uV: version 1.13.0.0
flash magic: version 5.91.2465

Thanks in advance!
