    very simple email support with a link to your post & the info/files.
    It doesn't have to be perfect, it just needs to be done in two weeks...

    This happened with a tune I acquired when using the stable release but the Beta opened it fine.
    I am not the guy that tunes transmissions, our username is similar. If yo message me about I am not replying anymore.
