i downloaded this thinking it looked & sounded like what i needed & i figured i'd rustle up the money if i coudl try it out enough to make sure i could use it... but the app won't even open! i keep getting a popup asking me to register or continue the free trial, but no app shows as being open in the dock, and no app appears!!! so how can i try it out to see if it even works? i can't even open it enough to find out what the terms of the trial are! ANNOYING...
