To say this is frustrating would be the understatement of the century. Yesterday, I uninstalled both Calibre and ADE. Downgraded to ADE 3.0 because I read somewhere that it should work better with an "older Nook" (I have the Glowlight, second version). I also redownloaded an older version of Calibre (2.2) because that is what is on my other laptop which I've had no issues with. I also used the 32 bit version because I also read somewhere that the 64 bit version may cause issues.

Voila! Success! Thought I was good to go.

Got up this morning borrowed a couple more books which open fine in ADE, transferred to Calibre and Nook and got "This book has been returned. Loan not on record." I have changed nothing since it was working yesterday. I've not de-authorized/re-authorized anything....The book will work if I load to my Nook directly through ADE so is the issue within Calibre?

This is driving me crazy.
