When a new update is available, the system will tell you the next time you launch the app. If you think an update is available, and didn't get the pop up window to upgrade the software, you can check for updates in the application's menu. If you're having trouble updating, try going to our website and downloading a new copy from there.
All updates a free and upgrades (when a completely new version of the app is released) are available at a discounted price for returning customers (but are very infrequent).
