I've downloaded the tool, get my mod successfully connected, but I can't select the file like the tutorial shows. It opens a blank window with nothing for me to select. I've checked the directory, and the .HEX file is present, I've tried redownloading, launching as admin, with and without batteries in mod, nothing works. I'm unable to update it simply because the program can't seem to find the .HEX file even though it is there.
