"Specified file is not valid Intel HEX file"

Hi - ( am not sure if this is the correct place to post this query, kindly help if anybody has a solution)

When I try to download a hex image thorugh AVRJATG ICE MK II on Chipcon 2420DB board, I get the following message and download is unsuccessful:

"The specified file is not a valid Intel HEX file"

I am using the AVR Studio 4, IDE

However I am able to read the flash memory of the board. And can successfully download the read hex file.

Please help,

Thanks
Mahan
