The software is defective. The claimed manufacturer and tech support provider no longer accepts claim for this software. In order to use the software and download it I am instructed to list my name with Knowledgeadventure.com per use of modem which goes to the company "Knowledge Adventure." However, as Knowledge Adventure Inc., is no longer is affiliated with this software and has no idea who is (but will give plenty of run around) I can't sign in and download the software. Therefore the software is useless. I suggest the ceasing and desisting of selling this product. To claim this product currently has any affiliation with Knowledge Adventure as you are led to believe by the packaging and manual is a total lie!!!
