I mistakenly authorized my tablet with a second adobe ID so now I can't download books I downloaded to my PC with my normal adobe ID. I tried to deauthorize the tablet but I can't bring up the section to deauthorize it. I was told to hold down the control/shift/D keys simultaneously and that would bring up the deauthorize option but the tablet keyboard won't let me do that. When I hit control it brings up another keyboard. Is there any other way to bring up the deauthorize option or for me to deauthorize this device so I can authorize it with the correct adobe ID. Thank you for any help.
