Yes, this version is supported - simply click "YES" when the popup for the update appears, and click YES again if the User Access Control prompt (where the screen dims to a dark grey in the background appears).
The application is safe and legitimate; we do recommend updating, as there are a number of new fixes introduced.
Thanks for writing!
