Unable to log on teamviewer after upgrading to teh latest version

As teh title says.I had teamviewer v14.1.something, tried to update to 14.2.something( dont remember teh exact number), and afterwards I keep getting teh message "unable to log in - please check your internet connection".Uninstallation and installation of a previous version(v11) didnt help.Internet works fine for anything else I try to do on teh PC, and I can log on using Teamviewer management console in chrome.Any help would be appreciated.
