This issue has many causes, but the most common ones are related to the registry and wrong configuration between the current installation and the update. My advice is to completely remove the application from your PC, clean the registry items and then reinstall the latest version of the application.
To clean the registry items, use CCleaner, after it has been uninstalled: http://ccleaner.software.informer.com/
To download the application you can either use the Lenovo Support and identify the product model or you can use the following link to download it: http://support.lenovo.com/ro/en/downloads/ds007940
