You can always contact us to purchase upgrades or inquire about them (click here for contact information).
When you have purchased an upgrade from one edition of the program to another (e.g. Classic to Pro Single, Pro Single to Gold Network, or additional licenses for Gold Network), you will need to re-register your software to activate the new features or licenses, which means you will need to get new authorization codes.
To do this, go to the Tools pull-down menu and choose Register, and follow the instructions there (call 1-888-590-1696 and choose the option to Get Codes there, or go to our website at http://www.camelotsoftware.com/OrderForms/CamelotCodes.htm).
