Good but frustrating

This is one of a series of programs from this company. I d/l the free versions but at every step you get interrupted to create accounts or upgrade or limit reached. You cant get a good sense of how it all can help. You want to sell this right? Give people one set. Let them complete w/o bugging them. Then, give the option to upgrade individually or as a bundle. Keep it simple. It think this is a good program. You can easily sell. Dont try so hard to sell!
