Yes, maybe
1. Silly, but is WIFI on? otherwise reg. must fail! Did you register this or other devices more than 6 times allover? If yes, mail to Adobe to reset your Counter, it's no problem at all, I did it yesterday for the 2nd time
2. 2.1.1 should support ADE, but I don't get it working. No loss if you have Aldiko, see above
