I've checked the official website and it appears that the software is working just fine which means there is a problem with the version installed on your computer, with the apps on your computer or with the settings that are configured within your application.
I recommend downloading a new version of the software through the proper channels.

I've mentioned proper channels because there is no direct link provided, instead they offer the option to find a reseller close to your area.
