Unfortunately, there are multiple causes that make CloneDrive stop working right. I suggest you perform a fresh installation of this software. Go to Control Panel > Uninstall a program > search CloneDrive and hit uninstall. After that, go to its official webpage and download the latest version of this software. If you still have the same problem after installation, I suggest you try another drive clone application like: Drive Cloner Rx.
