I just bought a new computer. ADE 4.5.6 downloads and installs just fine, it even let me authorize my computer. Now however it keeps "Not Responding" when I try to open the program or a book I got from the library. I followed advice from the forums and downloaded ADE 3, which does work, but has not had any security updates since 2014!
In this day and age, computer security is a must. I feel that Adobe either needs to provide new security updates for ADE 3 or how about FIXING ADE 4.5.6 so it WORKS!
And heaven forbid that you are actually allowed to speak to an actual person about this, because ADE is a free program, so nope, sorry, can't actually let you SPEAK to anyone.
