P. 115 states that you can upgrade your Rosetta Stone software for $10. That is an error. The actual cost is $20.
When a client has upgraded their computer and the Rosetta Stone software no longer works (i.e. they now have a newer Windows or MAC) OR if they want the latest version of Rosetta, the client is able to upgrade for a $20 fee. They should call 800-788-0822 and ask for Customer Service. They need to state they bought RS from Sonlight, and the company will verify this.
