Unfortunately, there is no information about this software. The official website uses another product, while Computer Age Dentist can't be found. However, firstly I recommend checking the official help. Since this might be a common error, press F1 and then go to Help and read about data modification within the program. This appears to be the only way possible regarding this software. Secondly, contact the new developer using the following address: http://www.carestreamdental.com/us/en/company/Contact%20Us#Contact Us
Since it's launch, the developer has been acquired by other companies, and it's now called CareStream Dental.
