What's the difference between "trail one" and "purchased one"?
Q: Would you please tell me the difference between "trail one" and "purchased one"?
A:The trail one just has 30 days validity, after that the flip E-book effect will be lost. But if you have purchased this software from us and get a key code,then the effect is effective forever. So there is no need to worry about losing the flip book effect. However, when you update the software in the future, the key code is still the same and valid.
