Jason, did you make any progress on the LDT files? I just want to make sure that my uploaded file at least has codes for the right number of keys, in case I ever need to restore from it. I do notice there is more data in it after I learned 11 devices than after I learned 5 devices, and at least the file is readable. Since I have never gotten an operating program upload to copy all the data correctly, I am skeptical. (The operating program when uploaded contains actual readable source code -looks like Visual Basic - right in the middle of an otherwise binary file)
