Livescribe periodically updates smartpen apps (such as Paper Replay) and underlying smartpen firmware. Livescribe also updates this software to support new kinds of Livescribe Dot Paper.
When you dock your smartpen and launch Livescribe Desktop, it checks for available updates. You can also manually check for updates using Livescribe Desktop.
If you try to use a new Livescribe Dot Paper product, and get an error message that it is “not supported”, you need to update your smartpen software.
