I have just bought a new computer and installed ADE. However ADE does not recognise my Kobo and the drop-down authorisation menu is greyed out. In addition, when I download books into ADE I can't do anything with them and, when I close the app and restart it, the books are gone. I have also been getting a message saying a problem has caused the program to stop working correctly. I have no problems downloading books into ADE and transferring to my Kobo from my old computer. Help!
