For 15 days, use the full SmartGo program free without any restrictions. The only difference to the registered version is a reminder dialog a startup.
At any time, you can purchase a serial number and activate SmartGo.
After 15 days, if you don't activate SmartGo, some important functions will be disabled, and others will degrade. SmartGo essentially becomes a Viewer. Please see below for the functions you'll lose.
