Why does Adobe Digital Editions continually stop working ?

All of a sudden Digital Editions stops working. I have uninstalled and re installed it 4 times and it still stops working. I have contacted support and waited for over an hour, talked with 2 different techs and they suggested that I look in the forums for an answer. HAVE NOT RESOLVED THIS ISSUE. I cannot use my e reader, which is my lifeline to the world. Any suggestions on how to resole this issue???
