Error! Check activation in ADE. I have been using for a year now. Tried to deactivate won't allow me to how to fix this so I can read a book?! When I try to erase activation. I get this error. Unable to deactivate try after some time. I have tried several days in a row and still get no where. I deleted ADE and reloaded it and still get no where. I tried the "help desk" and was told they can't help me that I need to check with forums please help!
