Hmmm.... I take it that you used the IFI Loader program on your PC connected via a serial port to the controller, and that you used the IFI Loader's "BROWSE" button to select the new .hex file for download, and before you could hit the "DOWNLOAD" button, IFI Loader said the file was invalid. Is that right?
I tried downloading a .hex file designed for one controller board to a different type of controller board and got a message about the processor being the wrong type (or something). But I think that is different than what you are seeing.
Try the IFI website -- browse their FAQs. You could try calling them (number below) -- they are nice guys, but be extra nice to them today as I expect they are getting overloaded with help requests.
