In order to fix the problems, I recommend that you remove the software from your PC using TuneUp Remover tool. Also, you can uninstall it with the help of Revo Uninstaller. Even if it can't uninstall the application normally, it will wipe out all traces of program's presence from the system. If you want to remove the software using Add or Remove programs feature, you need to reboot the computer and press the F8 key to enter in Safe Mode. After that, you will be able to uninstall the software using the classic procedure. Once you remove the utility, you can download and install its latest version from the official website.
