Hello,
I did the update for the flashpro. I am not longer able to upload a tune. The “upload” button is not highlighting when I open the tune I choose. I have been uploading e-tunes all week with no issue but now I’m unable to. What am I doing wrong?

With everything plugged in and the ignition in the on position, go to the Help menu and click on “send feedback”. Include a detailed description of the issue.
