You are in luck!
Your problems are over as you found the solution. All you need to do is to clear the “Secure Storage” contents. To do that go to

This should resolve the issue next time you try to update/install the plugin you should be asked again for your credentials to the BlackBerry developer portal and once you put them in the installation should proceed normally.read more
