Support Failure

I used this app for a year on my Mac Mini, with it doing just what it was designed to do. But the last week the app will no longer turn on Time Machine, only telling me to install the helper app. I have done this several times with the same result. I then began to email the developer at the support email address. To date no response after multiple emails. I held off writing a review to give the developer time to fix the issue, but the silence is telling.
