I assume you started with one of my definitions files so when you opened it excel should automatically go into compatability mode. Does it say [compatability mode] in the title bar when you have the file open?

I did try it again without the blank cells, and it was in compatibility mode. When modifying the definitions file in the ecutuner program, it worked, and read the correct information from the correct addresses but it couldn't save it either.
