@iDoug: found the bug (for some reason the program worked fine on my Macbook Air but not on an older Macbook). Anyways, it’s fixed and the firmware updater has been streamlined, mainly consolidating all versions and pulling the executables out to make them more obvious. Please download the new package from here:

Let me know if this works. Thanks.
