Reinstall Pemicro MSD bootloader after mbed bootloader

When I first got my frdm-kl25z board I was able to load the .srec files from the quick start zip file.  Since then I installed the mbed bootloader and have been successfully using that as well.  I'd now like to go back to the pemicro loader so I can try out coding using KDS, but I'm running into problems.  Here is what I have done:

 

1) reboot board to bootloader

2) Drag "BOOTUPDATEAPP_Pemicro_v111.SDA" into msd

3) reboot board again (this time it comes up in bootloader)

4) Drag "MSD-DEBUG-FRDM-KL25Z_Pemicro_v114.SDA" into msd

5) reboot board again

6) trying to drag ANY srec onto MSD

 

The small green led flashes, but the program never takes.  Readind the text file in the MSD says "Error 7"

 

Any ideas on how to get back?  I can put the mbed bootloader back on and everything works as it did before, I just can't get the KDS srec version to work again.  Thanks
