Adobe DE is just unusable

[sirmace]

Why don't you make this program where it is usable? I see many unanswered questions regarding my problem, and still the program is not fixed nor the questions addressed. I must conclude that there IS no answer nor solution to the inutlity of this program. I have been reading all the information aboutauthorizing ADE, de-authorizing, and reauthorizing. I even changed my user ID here at adobe.com to an email that I KNOW has never been used, but this **** program still tells me it cannot authorize my computer since the email has been used before. It's probably time to just give up and throw it out, isn't it?
