I downloaded the pro for a 1 month trial, but I realized I would like to do the school version. How do I switch and prevent from being charged for both versions if I decide to keep Earmaster after one month?
You are free to try both the Pro and School version. Both trial versions are free of charge and may be distributed freely. To continue using EarMaster (Pro og School) after it expires requires that you buy a license but we will not charge you for anything unless you decide to do so
