I've purchased this app many timesover the years and pay one price and own it till the next version came out. During the year you would receive updates which were fixes to the bugs that were in the program (NO CHARGE) I first purchased adobe was in 1993 and every year or so. Now it's a constant money grabber every month if not more often. And it broke down in many parts. I don't know about anyone else but I can't afford this but can't do without it. Somebody make a pdf app for one price for all.
