the lifetime full licence is a consumer trap
The software randomly drops the lifetime full licence code and defaults to the trial mode. The software is buggy. Worse, the lifetime full licence code can only be registered limited times and then it is voided. You will need to buy another licence code through no fault of the enduser. There is no guarantee that another lifetime full licence code will not be voided. In other words, the enduser is held to ransom. The lifetime full licence is a consumer trap.
