Clone Dvd program won't open



I have a shortcut for Clone Dvd on my desktop. When I click to open it, nothing happens. The clone dvd box appears on my toolbar, but it will not open. I open the clone dvd folder, and I still cannot open it. I have restored my computer to an earlier date, and this fixed it, briefly. Now it does it again. This happened previously, and I think I had to uninstall all versions, and download and install again.
Any idea why this might be happening? thanks
