ADE 4.0 would not open at all - no error. uninstalled that version and re-installed ADE 2.0, no the application starts but I am unable to download any library book , receiving this error
"Error getting license.License server communication problem: E_AUTH_BAD_DEVICE_KEY_OR_PKCS12"
At least 4 other people seem to have this problem within the last 24 hours - where is the response from ADOBE ????
This is supposed to be a reliable product, world class quality - definitely needs improvement on COMMUNICATION especially to a kind of spreading issue like this !
For this problem, you need to deauthorize and authorize ADE again.
Press keyboard shortcut: ctrl+shift+d
ADE will be deauhorized.
Now again AUTHORIZE ADE
Help-> authorize computer.
Error will be fixed !!
