Hi,
that is why most people take a test drive first, before they buy a new car or look out for second opinions. If the new car doesn’t fit your needs, you won’t buy it either. avast! also offers a 30 days test period. I am not saying, that bugs won’t need to be fixed or that there is plenty of time to fix them, but in the first place you could have ruled out those basic needs of your network / concept, since to me they seem to be more or less discoverable in the test period.
